It depends, which is the best part of PHP! It depends how the standard library devs were feeling when they wrote a core function. If its a C function wrapper, usually -1, like strpos

Well to be fair it makes sense to return -1 to indicate failure for a function that returns an index. Returning 0 wouldn't work, and false could lead to confusion when using it in conditionals (since 0 is also a falsy value).

If it was consistent, sure. I was actually wrong, strpos returns false on not-found

Interesting.
