The major issue is probably [\d\D]*? which matches everything (ie digits and non digits == everything) and then backtracks. Anyway your REs are a bit ugly. OK really ugly. There is also absolutely no reason to use $r_file as you never pass $file outside of 'main'. Also you have a useless set braces.

If you post what you want to do ie input/change file/output then I am sure you will get plenty of help. We need to see the exact input data, exact change file data, and desired output. </code>
