strpos is great for finding the first occurrence of a string, but what if you want the second? Or
third?
Easy enough:
<?php
function strposn($haystack, $needle, $num = 1, $offset = 0) {
for ($i = 0; $i < $num, $i++) {
$x = strpos($haystack, $needle, $offset);
if ($x === false) {
return false;
}
$offset = $x+strlen($needle);
}
return $x;
}
?>
