Measuring page load time with PHP

A simple method to view a PHP pages load time in seconds can be done with the use of microtime().

Microtime when called counts in microseconds, using microtime true makes it a float value rather than string.

Put this line at the start of your page:

$start_timer = microtime(true);

That will start the “timer”, then at the end of the page we can get the time taken from when $start_timer = microtime(true);  was called and use round() to format the microseconds better.

$time_taken = round((microtime(true) - $start_timer), 4);
echo "Page loaded in $time_taken seconds";

This will output onto your page something similar to Page loaded in 0.0017 seconds

Thats it! A short and simple way to view PHP page load time in seconds.
