matching patterns

[qrt123]

Hi there

I have a piece of code I want to act like this:

I have a variable: The content of that variable is a text-string.
If that string contains certain patternor words, the script must exit or else the content is moved to a database.

Okay, how do I check that string??

sincerely

hmm, cant you use [man]preg_match/man since you mention patterns?
