Counting your website's loading time using PHP

Counting your website's loading time is very useful and helpful for you to know that you need to make it more efficient or not.
Here, in this tutorial we are going to use PHP microtime() function to get the time and we'll be formatting it using number_format() function.
PHP code:
<?php
$mt = microtime(true);
        $format_time = number_format(microtime(true) - $mt, 2)." Seconds";
echo $format_time;
?>

If you are trying this code block on your on a blank page then probably you'll get 0.00 Seconds in results.
So to test it on a blank page follow this block of code:

PHP code:
<?php
$mt = microtime(true);
file_get_contents("http://www.thecodepress.info");
        $format_time = number_format(microtime(true) - $mt, 2)." Seconds";
echo $format_time;
?>

I'll always recommend you to use this but if you don't want to display it on your website then you can do something like commenting it something like this:

echo "<!--".$format_time."-->";

So after using that method the seconds will display in your website's HTML source code.
Another method which some other sites are using is to add the seconds at the bottom of the page (footer) you can too follow that.
