Question about strpos: how to get 2nd occurrence of a string?

Question

I understand that this function will get the first occurrence of the string.

But what I want is the 2nd occurrence.

How to go about doing that?

Answer 1

Simple is beautiful

function strposX($haystack, $needle, $n = 0)
{
    $offset = 0;

    for ($i = 0; $i < $n; $i++) {
        $pos = strpos($haystack, $needle, $offset);

        if ($pos !== false) {
            $offset = $pos + strlen($needle);
        } else {
            return false;
        }
    }

    return $offset;
}

$offset = strposX($result, "\n", $n);

if ($offset === false) {
    $offset = strlen($result) - 1;
}
