You can use strpos() and update the offset value to be after whatever you just matched.

You must find by strstr(), get result and start finding from result for time when strstr dont find nothing new.

You can use for it: http://php.net/manual/en/function.strpos.php

For the last occurrence, use strrpos.

$lastPos = strrpos($haystack, $needle);

It takes an optional offset argument too.
