Query time result in MySQL w/ PHP

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 - 10 for brown. (0.11 seconds)

I tried to look for an example, to no avail. Here is an example of my code:

                    // prepare sql statement
                $stmt = $dbh->prepare("SELECT ijl, description, source, user_id, timestamp FROM Submissions WHERE MATCH (ijl, description) AGAINST (?)");

                // bind parameters
                $stmt->bindParam(1, $search, PDO::PARAM_STR);

                // execute prepared statement
                $stmt->execute();

For my current full text search using a MyISAM table engine. Any help would be incredible. Thank you.

$starttime = microtime(true);

//Do your query and stuff here

$endtime = microtime(true);
$duration = $endtime - $starttime; //calculates total time taken

This will give you the run time in microseconds.

this may be help you

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)

mysql> SHOW PROFILES;

| Query_ID | Duration | Query                    |

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

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.

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
