Question

Is there a AND operator for PHP – regular expression.

I’m trying to replace everything from document to ' AND ).

$output = preg_replace('/document.*\'/', '', $output);

Any idea how this can be done?

I’ve tried to find some tutorial for RegEX but I can’t find any good. If you have any good sites or book please give me a link. I googled a lot.

Thanks.

EDIT: Misunderstanding.

This is the code before replaced.

<p>document.write(unescape('
<embed src="XXXXXX" type="application/x-shockwave-flash" wmode="window" width="712" height="475"%.35" allowFullScreen="true" ></embed>
')));</p>

I want to make it look like this:

<p>
<embed src="XXXXXX" type="application/x-shockwave-flash" wmode="window" width="712" height="475"%.35" allowFullScreen="true" ></embed>
</p>

Replaced:

document.write(unescape('

and

')));

Answer 1

What you actually want is to replace two parts, and leave something in between over. To not make it match undesired parts, use explicit character classes:

= preg_replace("/document[\w.(]+['](.*?)['][);]+/s", '$1', $output); 

So it matches anything enclosed in (' and ') with varying amounts of the latter.
