Is there a way that I can get the time of a MySQL query (specifically with PHP)? The actual time it took to complete the query, that is.

Something such as: Results 1

    There are two possibilities I can tell you now:

    • wrap ->execute() with microtime() and measure it yourself, possibly wrapping whole "querying" code snippet within a class / function
    • run EXPLAIN query of that query and see if you can read some values from the returned data

    Hope that helps.

    $starttime = microtime(true);
    
    //Do your query and stuff here
    
    $endtime = microtime(true);
    $duration = $endtime - $starttime; //calculates total time taken
    

    NOTE that this will give you the run time in seconds(not microseconds) to the nearest microsecond due to get_as_float parameter being true. See this

    mysql> SET profiling = 1;
    Query OK, 0 rows affected (0.00 sec)
    
    mysql> DROP TABLE IF EXISTS t1;
    Query OK, 0 rows affected, 1 warning (0.00 sec)
    
    mysql> CREATE TABLE T1 (id INT);
    Query OK, 0 rows affected (0.01 sec)

    |        0 | 0.000088 | SET PROFILING = 1        |
    |        1 | 0.000136 | DROP TABLE IF EXISTS t1  |
    |        2 | 0.011947 | CREATE TABLE t1 (id INT) |

    If you are using MYSQL 5, you should better check SHOW PROFILE

    http://dev.mysql.com/doc/refman/5.0/en/show-profile.html

    and print the timings in php...or EXPLAIN the SQL statement which took longer or detail each query...by CPU etc
