Here is a function I sometimes use to log that will show you the time
that has passed since the last log entry. I find it very useful, so that
you can test a section of code's execution time simply by surrounding it
with calls to this function.
Maybe it will be useful to you.

function log_message($log_file, $log_message)
{
global $last_log_write;
# SET FORMATTED DATE
$formatted_date=date("Y-m-d H:i:s");
# IF THIS IS THE FIRST LOG MESSAGE
if (!isset($last_log_write))
{
error_log("[$formatted_date] [-----------------]
$log_message\n", "3", $log_file);
$last_log_write=microtime();
$last_log_write=explode(" ", $last_log_write);
$last_log_write=doubleval($last_log_write["1"]) +
doubleval($last_log_write["0"]);
}
# ELSE (THIS IS NOT THE FIRST MESSAGE), CALCULATE TIME SINCE LAST LOG

$curr_log_write=microtime();
$curr_log_write=explode(" ", $curr_log_write);
