Moral is PHP is faster than CGI-Perl.

Sometimes, We need to monitor that, Who is visiting our forum without logging in. People who struggled a lot with spammers on their phpbb board should need some monitoring script to trace the guests.

Save the below code as “infolist.php”;

<?php

include "config.php";

mysql_connect($dbhost,$dbuser,$dbpasswd);

mysql_select_db($dbname);

$sql = mysql_query("SELECT * FROM `phpbb_sessions` where

`session_user_id` = '-1' group by `session_ip` order by `session_time`

asc ");

echo ("IP Address - HostName - Start Time - End Time -  VisitingPage<br

/> ");

while(($result = mysql_fetch_assoc($sql)))

{

$r = $result;

echo decode_ip($r["session_ip"])  .  " - " .

gethostbyaddr(decode_ip($r["session_ip"])) . " - <b>" . date("M d Y

H:i:s",$r["session_start"]) .  " - " . date(" H:i:s",$r["session_time"])

. "</b>" ;if ($r["session_page"]!=0){

echo '<a href="/forums/viewforum.php?f=' . $r["session_page"]  . '"

target=_blank > Looking into Page </a>';

}

echo "<br />";

}

mysql_close();

function decode_ip($int_ip)

{

    $hexipbang = explode('.', chunk_split($int_ip, 2, '.'));

    return hexdec($hexipbang[0]). '.' . hexdec($hexipbang[1]) . '.' .

hexdec($hexipbang[2]) . '.' . hexdec($hexipbang[3]);

}

?>

Upload the infolist.php to the phpbb forum root folder.

Code will work fine on any phpbb 2.x.x release.

Hope, It will help someone who fights with blind spammers on their phpbb.

A simple socks proxy scanner php script, that uses to check a list of socks proxy servers’ online status.

Example:
123.234.12.32:3523
98.45.57.78:9823
23.32.44.23:3785
123.32.45.56:3453
34.75.56.234:9856

save above lines as “proxies.txt”.

Code:

$filename = "http://domain.tld/filename.ext"; //or a localpath.
$rel=file_get_contents($filename);
$ipset = explode("\n",$rel); // explode it based on your delimiter.
foreach($ipset as $ips)
{
$ipandport=explode(':',$ips);
//Porxy string format might be 123.156.189.112:8080
$host=$ipandport[0];
$i=(int)$ipandport[1];
$fp = @fsockopen("tcp://".$host,$i,$errno,$errstr,10);
// tcp:// because, socks4 uses TCP and socks5 uses TCP & UDP
if($fp)
{
echo("Result is $fp
“);
echo (“port ” . $i . ” open on ” . $host . “
“);
fclose($fp);
}
flush();
}

Recently we have got to a site called alpha software somewhere through google , found some very interesting funny pages there.

This Alphasoftware claims they are 10x-50x more efficient than the other scripting languages

and you can see more of this crap on their site http://www.alphasoftware.com/ )

But i dont get the exact reason why they use asp themselves for their homepage

http://www.alphasoftware.com/about/contact.asp

some people might argue that This is not asp , and they might have spoofed the extension with help of their web server mime configurations but Look at this

http://www.alphasoftware.com/resources/it_related_9.asp and take rest!

why do they use asp that is 10x less effiecient or slower than their AlphaSoftware.

Some more of their technology

“Application Hosting

Once you have built your web application, the next step is to host or deploy your application to the Internet or intranet so that remote users can access your application via a browser. “

So you need to buy all these

Alpha version 5, application server and a runtime

it will cost you Very minimum of 1097 $ (very cheaper than php which i got for free)

https://www.alphasoftware.com/shop/AlphaFive/index.asp?UserType=new&RTSEL=0&V8SEL=0&WASSEL=0

Making some software that eases the people’s hard tedious work is always good but yelling stuff like 100x faster than this,that ,everything makes us look bad of them.

look at this

“Microsoft Access, Visual Basic, FileMaker, PHP, ASP, JSP, Cold Fusion all have merit, but none can match the combination of power and simplicity that is the trademark of all Alpha Software solutions.”

Why ? i find ruby on rails / cakephp a lot easier than this stuff after seeing few of their demos,etc

and finaly their product doesnt look that impressive decide for yourself )

http://afas.alphasoftware.com/SamplePages/

we are not encouraging them so we didnt provide any link to there website

If you people would like to share some about this you can comment here, make it more fun!.

You can add Paypal button in your website easily.

DO NOT Scroll this page as it is.. Just download the IPN class file and read below. Else it wont looks nice.

I tried my level best to explain important code lines.

You can use that button for getting donation or selling some products. Here is one Paypal IPN class in PHP. It is absolutely easy to setup and use.

Download the compressed file and extract it in your document root.
download and use the Paypal IPN class

And you have to edit some lines in paypal.php
at line 37
switch ($_GET['action']) {

case ‘process’: // Process and order… // There should be no output at this point. To process the POST data,
// the submit_paypal_post() function will output all the HTML tags which
// contains a FORM which is submited instantaneously using the BODY onload
// attribute. In other words, don’t echo or printf anything when you’re
// going to be calling the submit_paypal_post() function.

// This is where you would have your form validation and all that jazz.
// You would take your POST vars and load them into the class like below,
// only using the POST values instead of constant string expressions.

// For example, after ensureing all the POST variables from your custom
// order form are valid, you might have:
//
// $p->add_field(‘first_name’, $_POST['first_name']);
// $p->add_field(‘last_name’, $_POST['last_name']);

$p->add_field(‘business’, ‘YOUR PAYPAL (OR SANDBOX) EMAIL ADDRESS HERE!’);
$p->add_field(‘return’, $this_script.’?action=success’);
$p->add_field(‘cancel_return’, $this_script.’?action=cancel’);
$p->add_field(‘notify_url’, $this_script.’?action=ipn’);
$p->add_field(‘item_name’, ‘Paypal Test Transaction’);
$p->add_field(‘amount’, ’1.99′);

$p->submit_paypal_post(); // submit the fields to paypal
//$p->dump_fields(); // for debugging, output a table of all the fields
break;

case ‘success’: // Order was successful…

// This is where you would probably want to thank the user for their order
// or what have you. The order information at this point is in POST
// variables. However, you don’t want to “process” the order until you
// get validation from the IPN. That’s where you would have the code to
// email an admin, update the database with payment status, activate a
// membership, etc.

echo “<html><head><title>Success</title></head><body><h3>Thank you for your order.</h3>”;
foreach ($_POST as $key => $value) { echo “$key: $value<br>”; }
echo “</body></html>”;

// You could also simply re-direct them to another page, or your own
// order status page which presents the user with the status of their
// order based on a database (which can be modified with the IPN code
// below).

break;

case ‘cancel’: // Order was canceled…

// The order was canceled before being completed.

echo “<html><head><title>Canceled</title></head><body><h3>The order was canceled.</h3>”;
echo “</body></html>”;

break;

case ‘ipn’: // Paypal is calling page for IPN validation…

// It’s important to remember that paypal calling this script. There
// is no output here. This is where you validate the IPN data and if it’s
// valid, update your database to signify that the user has payed. If
// you try and use an echo or printf function here it’s not going to do you
// a bit of good. This is on the “backend”. That is why, by default, the
// class logs all IPN data to a text file.

if ($p->validate_ipn()) {

// Payment has been recieved and IPN is verified. This is where you
// update your database to activate or process the order, or setup
// the database with the user’s order details, email an administrator,
// etc. You can access a slew of information via the ipn_data() array.

// Check the paypal documentation for specifics on what information
// is available in the IPN POST variables. Basically, all the POST vars
// which paypal sends, which we send back for validation, are now stored
// in the ipn_data() array.

// For this example, we’ll just email ourselves ALL the data.
$subject = ‘Instant Payment Notification – Recieved Payment’;
$to = ‘YOUR EMAIL ADDRESS HERE’; // your email
$body = “An instant payment notification was successfully recieved\n”;
$body .= “from “.$p->ipn_data['payer_email'].” on “.date(‘m/d/Y’);
$body .= ” at “.date(‘g:i A’).”\n\nDetails:\n”;

foreach ($p->ipn_data as $key => $value) { $body .= “\n$key: $value”; }
mail($to, $subject, $body);
}
break;
}

Save paypal.php

And use the below code to display paypal button image.

<form action=”paypal.php”>
<input type=”image” src=”https://www.paypal.com/en_US/i/logo/paypal_logo.gif” border=”0″ name=”submit” alt=”Make payments with PayPal – it’s fast, free and secure!”>
</form>
action=”paypal/paypal.php” change it based on your directory structure.

Every one needs to promote their website. So we takes care on the content, designing ,etc… after launching our site we will start getting more hits everyday. But we have to trace all the hits. We must log the visitors ip address and referrer address alltime. Because someone may try to attack your server based on url. Just log the details everytime. It will be fine for you.

Step 1:
Include the below code in your footer.php or in footer or header area of all of your pages.

$remote = $_SERVER['REMOTE_ADDR'];
$remote .= “–”;
$remote .= $_SERVER['HTTP_REFERER'];
$date = date(“d-n-Y”);
$remote .= “– “;
$remote .= $date;
$remote .= “\r\n”;
$filename = ‘home.txt’;
if (is_writable($filename))
{
// In our example we’re opening $filename in append mode.
// The file pointer is at the bottom of the file hence
// that’s where $somecontent will go when we fwrite() it.
if (!$handle = fopen($filename, ‘a’))
{
// echo “Cannot open file ($filename)”;
exit;
} // Write $somecontent to our opened file.
if (fwrite($handle, $remote) === FALSE)
{
// echo “Cannot write to file ($filename)”;
exit;
}
//echo “Success, wrote ($remote) to file ($filename)”;
fclose($handle);}

else
{
//echo “The file $filename is not writable”;
}

If you like to see the script’s status then just remove the comment lines.
Step 2:
Create a text file named home.txt and chmod it to 0777

We are just writing information in to a file using php. Just do the above two steps and start logging your visitors.

Form Design:

<form id=”form1″ name=”form1″ method=”post” action=”login.php”>
<table width=”300″ border=”0″>
<tr>
<td>Username</td>
<td><input type=”text” name=”username_field” /></td>
</tr>
<tr>
<td>Password</td>
<td><input type=”text” name=”password_field” /></td>
</tr>
<tr>
<td> </td>
<td><input type=”submit” name=”login” value=”Login” /></td>
</tr>
</table>
</form>

Save it as “form.html”

<?php
session_start(); #3
include(‘config.php’); //Listen #1
$username = $_POST[‘username_field’];
$password = $_POST[‘password_field’];
if(($username == $user) && ($password == $pass))
{
$hash = md5($pass); //Listen #2
$_SESSION[‘hash’] = $hash;
echo(“Welcome $username<br>”);
}
else
echo(“Incorrect username/password<br>”);
?>

Save it as “login.php”

Listen #
#1: We are just including one php script within this login.php.
Let us say config.php looks like below:

<?php
//Configuration settings
$user = “rob”;
$pass=”p123”;
?>

#2: This is the main code in login.php
md5(); is a function which generates hash code for given value.
We are assigning the hash value of $pass in to a session variable.

#3:
session_start(); we have to start the session in every page where ever we use session variables. It should be very first code of the script before producing any output.
For example:

<?php
echo(“First line”);
session_start();
—-
—
?>
This will produce an error. So it should be like

<?php
session_start();
echo():
?>
<html>
<head>
<title>title</title>
</head>
<body>
Html codes
</body>
</html>
<?php
echo(“last line”);
?>

Why we need Session variables?

Let us say, you are going to develop an admin panel or user area. We need to allow authorized users only in some pages. So we must check his authority at any time. We cannt put form every where to get username and password from user. We are getting username and password only once from user and keeping his identity in login.php and other scripts. So we are storing the hash value of his password in a session variable and checking it in all pages. Seems confusing? Ok see this example it may help.

<?php
session_start();
//Account Area
include(‘config.php’);
if($_SESSION[‘hash’] == (md5($pass)))
{
echo(“Welcome $user”);

}
else
{
echo(“You are not authorized to visit this page!”);
} ?>
Why we are checking hash instead of original password? Because there are some security problem with php register globals setting. This method is some what secured with session variables.There is a problem with this script. Can you guess? Yes this will stuck if any two of users having same password. Yes there is no chance for duplicate username. But there is many chances for duplicate passwords. So what is the solution? Yes we have to store the hash of username in a session variable and have to check it in everywhere.
Like below:

If(($_SESSION[‘username_hash’] == (md5($user))) && ($_SESSION[‘password_hash’] == (md5($pass))))
{
}

Sounds good? We are just getting username and password from a config file (config.php) you can manipulate this mechanism by retrieving username/password from database tables.

PHP Tutorial for people who is going to develop some real-time applications in PHP-MySQL . I am not going to say what is a variable and what is “for” loop syntax. If you want to know very basic about php then go to Zend PHP Tutorials . My tutorial is fully application based.

I assume that you know basic programming knowledge in php. Like for loop, while loop, session & mysql database connectivity.

Ok we are just going to develop one login system now.

What are the steps?

1. Get username & Password from user
2. Validate them
3. If valid then let user to use the system
4. else show an error message

These are basic considerations.

We can achieve this by writing a single php file.

1. PHP login form design

Design notes: Use tables to show form fields in aligned manner.

Code for simple table with 6 cells

<table width=”300″ border=”0″>
<tr>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
</tr>
</table>

I hope you know for printing a blank space. Enclose the table tags with a form tag.

<form id=”form1″ name=”form1″ method=”post” action=”login.php”>
<table width=”300″ border=”0″>
<tr>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
</tr>
</table>
</form>

Note: action = “login.php” login.php is current file name. you can change its name.

<form id=”form1″ name=”form1″ method=”post” action=”login.php”>
<table width=”300″ border=”0″>
<tr>
<td>Username</td>
<td><input type=”text” name=”username_field” /></td>
</tr>
<tr>
<td>Password</td>
<td><input type=”text” name=”password_field” /></td>
</tr>
<tr>
<td> </td>
<td><input type=”submit” name=”login” value=”Login” /></td>
</tr>
</table>
</form>

Note: input type=”password” because Password field will carry password characters.

You know these are just <html> tags.

<?php
$username = $_POST[‘username_field’];
$password = $_POST[‘password_field’];
$user = “user1”;
$pass = “123456”;
If(($username == $user) && ($password == $pass))
Echo(“Welcome $username<br>”);
Else
Echo(“Incorrect username/password<br>”);
?>

Note: $_POST[‘username_field’]; and $_POST[‘password_field’]; are POST method values. $user & $pass are variables which holds the username/password.
Continue to page 2
This is not a full login system. This is for showing how it will be.

PHP is the leading server site scripting language. Most of the websites are migrating from Cold Fusion, ASP and JSP to PHP. Because the fast, flexibility, database support and so on makes PHP best.

What is PHP?

PHP (PHP Hypertext Preprocessor) Personal Home Pages in earlier days.

PHP cannot run like C, C++ or any other programming languages. PHP is a Server side scripting language. So you have to install and configure a web server with PHP. Apache is the most commonly used web server.

You can download and install Windows/Linux/Mac versions of PHP and Apache. But configuring PHP-Apache won’t be easy for you as a beginner. It is all about editing configuration files and moving files. It may take ages for you to configure and run a “Hello World” programming.
Download WAMP

Best solution for php beginner level programmers .

WAMP Server (Windows Apache MySQL PHP)Download Wamp

Download PHP tutorial in pdf format

Just download and install it. Start your wamp server by left click on wamp icon in system tray (Place where the clock is available in Taskbar) > Apache > Start/Resume Service. This menu item will be disabled one WampApache is running. Ok Lets successfully installed WAMP and started Apache service.You have to understand very basic things about web programming. That is the words LocalHost, Document Root, index page,etc.
Localhost: simply your computer.

You can see what web service is running in your computer. Just open IE (internet Explorer) or Firefox and type http://localhost in the addressbar. You will get an index page about the current localhost. We are currently installed Apache web server with WAMP. So we will get wamp homepage. You can install some other PWS (Personal Web Server) IIS (Internet Information Services) is the default web server for Windows.
My First PHP Program:

Open a text editor.
Start->Run->notepad

<?php
echo(“Hello World”);
?>

Just type the above code and save it as a php file.
Where to save?
You must save all of you PHP files under Root folder. Your document root may be “D:\wamp\www\” folder. So save your file under this folder.

File type?
All PHP files should be saved with the extension (*.php) by default.
Change the “Save as Type” list box’s value in to “All Files” in “Save as” dialogue box. And give the filename “first.php” (without double quotes) and click “Save” button.

Just type http://localhost/first.php in your favorite browser.
Output should be

Hello World.

Once you got this output then your PHP presence is started with cheers!
