you can write one:
[code]
<?php
function getExt($filename) {
  $pos = strrpos($filename, '.');
  if ($pos !== false) {
    return substr($filename, $pos + 1);
  } else
    return NULL;
}
?>
[/code]

in the other example (linked site) they use a function called: strch() but that returns an undefined error wierd

Look at the [a href=\"http://www.php.net/pathinfo\" target=\"_blank\"]pathinfo[/a]() function.

Example from the manual:
[code]<?php
$path_parts = pathinfo('/www/htdocs/index.html');
echo $path_parts['dirname'], "\n";
echo $path_parts['basename'], "\n";
echo $path_parts['extension'], "\n";
?> [/code]

they are trying to use strchr(), but it's simply an alias of strstr() anyway
