Note Submitter: logico AT avantel . net ---- If you want a recursive function that counts the amount of occurrences of a string within another: function occurrenceCount($word, $string, $case_sensitive = true, $actual_count = 0){ if(!$case_sensitive){ $as = strtolower($string); // Actual string $aw = strtolower($word); // Actual word } else { $as = $string; // Actual string $aw = $word; } $as = strstr($as, $word); if(!$as){ return $actual_count; } else { $as = substr($as, strlen($aw), strlen($as)); // Let's remove the searched word from the beginning of the string return occurrenceCount($aw, $as, $case_sensitive, ++$actual_count); } } Just call it: echo "Ocurrences of 'dog' within 'eat your own dog food' is: ".ocurrenceCount("dog", "eat your own dog food");
