Execution Time of a file?

[Dark_Phoenix]

I was going to run a few tests of speed to see whether certain methods are better than others, when I realized something; I didn't know how to access the execution time of a script! After browsing the manual, I still haven't found it. Is there a function or variable which tells you the execution time of a script?

a very quick search on Google.com returned these results

I have a php script that returns about 1.5Mb of data in text format to the
user. I am wondering if there is a way for php to display the time it took
to execute the script at the end of the file.

Put this at the top of the script:

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

$time_start = getmicrotime();
</code>

..and this at the end:

<code>
$time_end = getmicrotime();
$time = $time_end - $time_start;
$foo = round ($time, 2);
echo "Execution took $foo seconds.";
</code>

Hope this helps.

Best regards,

Jome
