Re: [PHP] Getting MySQL Query Times.
Use microtime before and after the query.
$this-starttime=explode(' ',microtime());
// query()
$this-endtime=explode(' ',microtime());
$this-starttime=$this-starttime[1]+$this-starttime[0];
$this-endtime=$this-endtime[1]+$this-endtime[0];
$this-parse_time=$this-endtime-$this-starttime;
I've copied from working code of a class. But the idea is clear.This way is
better than time() solutuion because with microtime() you get microseconds.
But have in mind that on windows there are some problems with microtime()
and the reported time can be negative.

Subject: [PHP] Getting MySQL Query Times.
I was looking thru the mysql functions, and there doesn't seem to be one
that gives you the amount of time a query takes. Is there anyway to get
this information (since it gives it to you when you type queries
directly into the mysql shell client)? A script of mine is starting to
get fairly slow (2-3 seconds for page to process) and I want to be able
to log the query speeds so I can see if there's a database bottleneck or
if my code is just kludgy.

Re: [PHP] Getting MySQL Query Times.
IMO, you are better off printing microtime [http://www.php.net/manual/en/function.microtime.php] before and after the query, and after you loop through it. This will give you a better idea of where the hangups may be. You may also want to sprinkle mircotimes throughout your code to get a good idea of processing time.

I don't know if there's an actual function for it (although I wouldn't be surprised, knowing PHP :-), but you could definitely do something like: $start = mktime(); $sql = SELECT foo FROM bar ORDER BY xyzzy; $result = mysql_query ($sql); // do something with the result if you want that timed as well $end = mktime(); $total = $end - $start; echo $total; // could format this using date() if you fancy HTH Jon -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP] Getting MySQL Query Times.
Thank you Andrey Nathan. THat was probably going to be the next thing to research. I think I figured out why my code got slow though. I have a preg search of a large field with .* in it at the beginning of an if,elseif,elseif,elseif struct that I should move to the end of it.
