use this.

$d=preg_replace("|<script type=\"text/javscript\"(*.?)</script>|is","",$d); 

It will remove all javascript code matching ths sequence.

$hammad = preg_replace('/<script(.*?)<\/script>/is','',$hammad);

$hammad = preg_replace('/<a href="http:\/\/ad(.*?)<\/a>/is','',$hammad);

use this.
$d=preg_replace("|<script type=\"text/javscript\"(*.?)</script>|is","",$d);
It will remove all javascript code matching ths sequence.

you would get problems using this code. as you need to make sure you escape slashes.

$hammad = preg_replace('/<script(.*?)<\/script>/is','',$hammad);

$hammad = preg_replace('/<a href="http:\/\/ad(.*?)<\/a>/is','',$hammad);

i would use this version hammad has offered up. its correct

[zain]

thank you guys

You don't need to escape the forward slashes if the delimiter isn't a forward slash.

Tube is a alternative meta-character so it shouldn't be used as delimiter.

ok your right to some extent.
but if you took the time to read the 2 comments left in that link you posted.
you'd see its not a wise choice or idea to use meta-characters in the regular expression
as a delimiter, thats not saying you cant use them. i was just clearly stating that the option
hammad offered up was clearly the better of the 2 choices given to this original poster.

Try to avoid using these:

. \ + * ? [ ^ ] $ ( ) { } = ! < > | : -
