I'm currently coding a search engine, and everything seems to be going smoothly, until I reach regular expressions (I hate them so much..). So far, the script can crawl a site from an array, and grab a sentence with the keywords. However, it's a bit messy, and I wondered if someone would be so kind as to show a pattern that would do it properly.
Basically, I need a pattern that matches a sentence with letters and numbers only (to filter out HTML) and with the sentence must have this in:
Here's the code I'm using at the moment:
/$pieces.*/I must say it's not too good.
Any help greatly appreciated,
