Question

What does Warning: strpos() [function.strpos]: Empty delimiter in mean?

I have this:

    if(strpos(''', $text) === false)
    {
        $text = str_replace(''', "'", $text);
    }

Answer 1

At a guess, I’d say $text is an empty string (thanks Mark for pointing out the specifics)

Edit: Also, another guess is you have the parameters in the wrong order. The method signature of strpos is

int strpos ( string $haystack , mixed $needle [, int $offset = 0 ] )
