String Contains Function

[j1mb0jay]

Is there a function in PHP that will return a boolean if a String
contains another given String. As what I am trying to do is disallow
input that contains ../ or something else that would allow directory
traversal.

strpos()/regex etc. could be used for this, however, I'd use realpath() on
the results to check wether it's still 'safe'.

Did not think of the realpath() function.

Thank you.
