• Answer:

  Without the complete and specific requirement, I can not give you a working solution. But the idea is straightforward: use regular expression to do the matching (based on your criteria) and extraction. something like the following, but I didn't try actually running it: $pattern = '@https?://[a-z]{1,}\.{0,}([a-z]{1,})\.com(\.[a-z]{1,}){0,}@' preg_match($pattern, $s, $matched); print_r($matched); you most likely want to modify the $pattern regex to match your requirements
