Question

I am using PHP & want to parse given string:
Let say

$str = '<object width="640" height="385"><param name="movie" value="http://www.youtube.com/v/W-WKYIgGBbU&amp;hl=en_US&amp;fs=1"></param><param 
name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param>
<embed src="http://www.youtube.com/v/W-WKYIgGBbU&amp;hl=en_US&amp;fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" 
allowfullscreen="true" width="100" height="100"></embed>
</object>';

and I just need

$output = '<embed src="http://www.youtube.com/v/W-WKYIgGBbU&amp;hl=en_US&amp;fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" 
allowfullscreen="true" width="100" height="100"></embed>';

and set height and width to my custom value let say $width = 30 and $height = 40.

Thanks..

This should work:

preg_match("/<embed.*\/embed>/mi",$str,$matches);
$output = preg_replace(array('/width="\d+"/i','/height="\d+"/i'),array('width="30"','height="40"'),$matches[0]);
