[SOLVED] substring

[Asday]

I've looked up substring on google, but I don't quite understand.

 

Case:  I want to disallow anything starting with "http://"

 

I've got this far: 

if ($_FILES["file"]["name"] !== // something

What you're looking for is substr

<?php
      $s = 'http://www.php.net';
      if (substr($s, strlen('http://'))) {
            //code ... it starts with http:// ... so what to do?
      }else {
            //code ... it doesn't start with http:// ... so what to do?
      }
?>

Thanks!  That worked (Had to fiddle with it to get it to work with my existing code)

 

<?php
if (($_FILES["file"]["type"] == "image/gif")
// ...
&& ($_FILES["file"]["name"] !== (substr($_FILES["file"]["name"], strlen("http://")))))
{
  // upload
}
else
{
  echo "Sod off.";
}
?>
