How can I split a string in PHP at the nth occurrence of a needle?

Question

There must be a fast and efficient way to split a (text) string at the "nth" occurrence of a needle, but I cannot find it. There is a fairly full set of functions

Answer 1

Easily, just do it:

$i = $pos = 0;
do {
    $pos = strpos($string, $needle, $pos+1);
} while(++$i < $nth);
