[Resolved] Checking if text is in a string

[bengt]

I have a string:
$ext_allowed = "RTF|DOC|ZIP|PDF|JPG|GIF|XLS|PPT|PPS";

$extension="exe";

How can I check if $extension does not exists in $ext_allowed?
Not case sensitive of course...

This should do it for you.

noods...

<?php

$ext_allowed = "RTF|DOC|ZIP|PDF|JPG|GIF|XLS|PPT|PPS"; 

$extension="rtf"; 

if (!strstr(strtolower($ext_allowed),strtolower($extension))){
	echo "string not found";

}
else {
echo "string found";
}



?>
