calculating the load time of a web page

[davehaz]

howdy,
does anybody know how to calculate the load time of a webpage using php?
thanks.

you could record in a table the load time everytime someone requests it, and then use an average.

[davehaz]

exactly what I wanted to do, but how do you get the load times to average?

[marek_mar]

There is an equation for the average.
Avarage = Sum of all values / Number of values.

There should be a few examples here (http://www.google.com/search?hl=en&q=php+load+time&btnG=Google+Search)

[davehaz]

actually Marek_Mar it would be

Average = Sum of all values / Number of values


thanks.

Of course there is no way to tell if the person waited for the whole page to load or whether they loaded the page without images so any stats you get will be fairly meaningless.

Do you mean like how google shows you how long it took to conduct a search? Or how on some sites shows you how long it took to long and how many different queries were used? You might want to start looking at this function. Also check the comments below. Microtime (http://www.php.net/microtime)

//put at begining of file

function utime (){
$time = explode( " ", microtime());
$usec = (double)$time[0];
$sec = (double)$time[1];
return $sec + $usec;
}
$start = utime();

//put at end of page before body and html tags

$end = utime(); $run = $end - $start; echo "Page expelled in " . substr($run, 0, 5) . " secs.";
//Nothing after this
