Question

I would like to use mysql query profiler in the php script. So that after i execute any queries it need to display the execution time of the query.

Suggest the best way to use this also share any other scripts like query profiler.

Answer 1

Before:

You need to set the profiling to 1 before you execute your query in order to get access to the profiling information.

mysql_query("SET profiling = 1");

After:

After you’ve executed the query you want to test you need to execute the following query.

$a = mysql_query("
     SELECT query_id, SUM(duration) AS duration 
     FROM information_schema.profiling
     GROUP BY query_id ORDER BY query_id DESC LIMIT 1
     ");

//in case you want to loop through more than one profile
while($b = mysql_fetch($a))
{
    echo 'ID: '.$b['query_id'].'<br>Duration: '.$b['duration'].' seconds';
}
