which function would i use to check if a certain value is in the contents of
a variable?

I have a form where the users submits url's. I need the url with http:// in
the beginning. Since there is more data after the http:// i can┤t just do a
simple if-statement. So what do i do?

After i determined if there is a http:// in the variable or not i guess i
just have to $url = "http://"; + $url; (?)...
