Array help needed

Im using this little script to delete files older than XX mins in a dir.
How can i add multible file extentions/directories?
Thanks.

<?php
$captchaFolder  = '6pilased/10b/';

$fileTypes      = '*.doc';

$expire_time    = 14400;

foreach (glob($captchaFolder . $fileTypes) as $Filename) {

    $FileCreationTime = filectime($Filename);
 
    $FileAge = time() - $FileCreationTime; 
 
    if ($FileAge > ($expire_time * 60)){
 
        unlink($Filename);
    }

}
?>

Code (markup):

 

you should try by comma
$fileTypes = '*.doc, *.exe';

 

glob has a flag named GLOB_BRACE

source: http://gr.php.net/glob

so you can type

$fileTypes      = '{*.doc,*.gif,*.txt}';
...
foreach (glob($captchaFolder . $fileTypes) as $Filename, GLOB_BRACE) {
...
