How do I use profiling to find execution time for both SQL and MongoDB query in PHP? -

-

i'm new php , don't know how use profiling execution time of following queries. mongodb query:

$collection = new mongocollection($db,'customers'); $cursor = $collection->find(['customer_id' => intval($id)]);

sql query:

$s = oci_parse($c, 'select customer_id                     customers                    customer_id = :un_bv                   '); oci_bind_by_name($s, ":un_bv", $_post['customer_id']); oci_execute($s);

i tried following code mongodb query print lot of things of know nothing. 

$db->setprofilinglevel(2); $cursor = $collection->find(['customer_id' => intval($id)]); $response = $db->system->profile->find();  foreach($response $obj) {     print_r($obj); }

help me on how use profiling execution time only.

in general can use microtime() in php test execution time of piece of code, in case 2 queries.

see: http://php.net/manual/en/function.microtime.php
