Php provides us a very useful function to determine exactly how much time is needed for your php code

$start = $time;
?>

if you want to determine the time for particular part of the code put the above code before that
php code part.
the following script has to be put at the end of the web page or the end of the php code part.

<?php
$time = microtime();
$time = explode(' ', $time);
$time = $time[1] + $time[0];
$finish = $time;
$total_time = round(($finish - $start), 4);
echo 'the Page generated time is '.$total_time.' seconds.';
