Re: [PHP] Logging PHP Execution time to a file?

I use this function:
function echo_pt($add='') {
static $pt = 0;
if($pt==0) {
$pt = miro_time();
return;
}
$time_start = explode(' ', $pt);
$time_end = explode(' ', microtime());
$parse_time = number_format(($time_end[1] + $time_end[0] -
($time_start[1] + $time_start[0])), 3);
echo '<!-- Parse Time '.$add.': ' . $parse_time . 's -->';
$pt=microtime();
}

Usage:
it needs to be initialized first:
echo_pt();
then simply call as many times as you need:
echo_pt('some string');
and it will show you seconds elapsed from the last call to this
function, so you can easily see where the script spends most of its
time. Instead of echoing it you can append it to a file.

It seems to me that many people (usually CMS systems or shopping carts)
try to re-invent the wheel. The pear repository is filled with many
packages, hopefully more to come, and the Benchmark Package is one of
them.

require_once "Benchmark/Timer.php";
$timer = new Benchmark_Timer;
$timer -> start();
// Plenty of code...
$timer -> stop();
print("<!-- Total execution time: ");
print($timer-> timeElapsed());
print(" seconds. -->\n");
