    OK, not must but better maybe
    preg_quote
    If we have $MyRegExp="/<style>/"; to simplify:
    
$MyRegExp="/<style>/";
echo preg_quote($MyRegExp)."\n";
    PHP:
    Echoed
    However, this simple example gave warning and I'll check why when I've time for this.
    Regards

    It's certainly odd, that's for sure. I've never had to escape < or > and I've used the preg_ functions more times than I can count. Sure enough though, preg_quote escapes those characters.

    sorry, meant:

    preg_replace("/<style[^>]*?>(.*?)<\/style>/Uis",'$1',$html);
    PHP:
    Posted that last night and was tired.

    @koko5 test this:

    <?php

$html = <<<HTML
<style>
blahblah...
</style>
HTML;

echo preg_replace("/<style[^>]*?>(.*?)<\/style>/Uis",'$1',$html);

?>
    PHP:
