you can run shell commands eg:unix commands etc using exec() - which brings me to a question of my own, somebody once posted unix code for resizing an image - I have searched high and low for it - if anyone an point me in the right direction - it would be much appreciated.

The function exec() is for you to execute an external program. It lets you run commands that you would normally be able to run on your telnet account say. However it only returns you with the last like of the result.

<?
$string = exec("/bin/ls");
echo $string;
?>

The above example would be the simpliest i could think of =)

There's other functions like system() which would execute and then displays the output too. Just like the above example.. just swap the exec for system.
