Creating a PHP Script for Web Mail Posting and Notification - Page 2

HOW IT WORKS

A PHP-Script is being called from the mailserver and receives the incoming mail as standard-input. This mail is being forwarded to a URL via HTTP-POST, such as a regular entry to a web formular. Also, because of the .forward file you can forward the mail to other users automatically or you can store it in a folder of your choice.
In order to start a PHP-Script from Postfix or sendmail, it has to be processed just as a Shellscript. It should contain the directory of your php-interpreter, such as:
#!/usr/local/bin/php
Even though many are just using PHP as an Apache-module, the interpreter usually is installed in a self running file on the computer. On most computers you can find it in /usr/local/bin/, on others you can find it under /usr/bin/.
If you are labelling the created file as self-running (chmod a+x scriptfilename) and then start it, your php-sourcecode in the shell - just as a regular shellscript - should run.

OPEN THE ENVELOPE

Now we have to read out the standard input. As said above, Bjoern already wrote about this, and it is just as easy as opening a file. To be precise, a file such as "php://stdIn". This pseudo-URL allows you to read out the standard input as follows:

<?php
$res
="";
if (
$fp=fopen("php://stdIn""r"))
{
    while (!
feof($fp))
    {
        
$line=fgets($fp4096);
        
$res.=$line;
    }
    
fclose($fp);
}
echo 
"\n standard input was $res \n";
?>
