Check for condition "like"

[TSch]

Hi folks,

I'm currently trying to think myself into writing php scripts.
The current "task" ahead of me should be easy for you to solve ;-)

Question is:
I got an input box where someone can enter some text.
The input is being assigned to a variable. Now what I'd like to to is to check if the input contains a certain string and if that's the case perform certain actions ...

e.G. the script is supposed to check for the word "carmel" so that if someone enters "The carmel-mountain" the script recognizes the string "carmel" has been entered and performs certain actions ..

How can I do this ?

Regards
Thomas

Hi

For simple substring search use the [tt]strpos()[/tt] or [tt]strstr()[/tt] function ( or their case insensitive variant, [tt]stripos()[/tt] or [tt]stristr()[/tt] ). For more complicated expression use the [tt]preg_match()[/tt] function. See their documentation for details and simple examples.

If you have trouble with them, post your code so we can correct it.
