script execution timing

[Anon]

I've been running into a intermitent situation where my server sometimes bogs down/takes a very long time to execute scripts.

Does anyone have any ideas on how I could write a PHP script (executed by cron) that would calculate the time it takes for the script to execute ?!?

I could then receive a email alert whenever to execution exeeded a preset level (30 seconds) ?!?

Many thanks in advance.

You can use the microtime() function to calculate the script timing, like this:

<CODE>
function getmicrotime(){
list($usec, $sec) = explode(" ",microtime());
return ((float)$usec + (float)$sec);
}

$time_start = getmicrotime();

for ($i=0; $i < 1000; $i++){
//do nothing, 1000 times
}

$time_end = getmicrotime();
$time = $time_end - $time_start;

echo "Did nothing in $time seconds";
</CODE>

and also, use set_time_limit(0); to make the script as long as it takes to execute.
