query time?

[AaronV]

Hello,

I'd like to get the time it took a query to execute. Is there a PHP or
MySQL function that would return the execute-time of the query into a
useable format?

Similar to the way Google displays how long a search takes.

OK, so you can run microtime() before executing the query,
then again after executing the query, compute the difference,
and output the result.

The following example is based on code snippet given at

http://www.php.net/microtime:

function microtime_float ()
{
list($usec, $sec) = explode(" ", microtime());
return ((float)$usec + (float)$sec);
}

$time_start = microtime_float ();
$result = mysql_query('Yo ur query here');
$time_end = microtime_float ();
$time = $time_end - $time_start;
echo "The query took $time seconds";

Cheers,
