RE: [PHP] SQL Query time?
I wonder if using microtime() gives _actual_ time spent for the query while explain gives _processor_ time.

That depends on the SQL server you are using (and I'm not talking about M$SQL Server! :-) ). In postgreSQL you do that with an EXPLAIN query, but the results are given throught the warning output, and there is no function to grab it. But it wouldn't be difficult to build it. :-) Saludos... :-) -- El mejor sistema operativo es aquel que te da de comer.

Re: [PHP] SQL Query time?
Sup,
Adding explain before the select query will show you how long it will
take, along with some other info, but it won't actually give you the
results.
I use a the function microtime (http://php.net/microtime) to figure
execution time. When called, microtime will return a string with
miliiseconds then seconds seperated by a space. So you have to do something
like this...
function sn_Msecs()
{
$mt = microtime();
$mt = explode( , $mt);
return ($mt[1] + $mt[0]);
}
That will return seconds.milliseconds or something like 13123141.1231, it is
not in proper math form.
Just call it before a block of code or query, then call it after and
subtract the second one from the first.
SL.
