Question

I have a variable in my PHP code where its equal to a stored string.
A small portion of this string is taken and used as a preview on a different page.
On occasion there will be Javascript in that string, how could I say the following:

Pseudocode:
if stringVar contains "<script"
then remove the substring starting at "<script" and ending at "/script>"

If you’re just getting rid of script tags:

$result = preg_replace('%<script>.*</script>%i', '', $subject);
