Question

My latest issue involves trying to find “http://” in a variable. This variable contains the contents of a comments section on a clients website. I have seen all kinds of answers but none of them seem to work. I looked at a few other posts on here and I have yet to get the best answer. Here is what I have so far:

if(strpos($comments, 'http://') == true) {
  // Does stuff here
}

I noticed other people use preg_match and some said to do it in an array. I am getting confused, too many options. Just kidding. I would like some clarification though and any advice would be greatly appreciated.

Answer 1

You’ll need to say:

if(strpos($comments, 'http://') !== false) {

…since it can return 0 (which is falsey) if http:// is at the beginning of the string.

NOTE: This will only find the first occurrence of http:// in the string.
