PHP code execution time

Question

How to find my code execution time?

I am using the below snippet.

I am not happy with that?

list ($msec, $sec) = explode(\' \', microtime());
$mi         


        

Answer 1

Thanks for sharing your information.

The below one also LITTLE BIT near of my solution.

function microtime_float() {
    list($usec, $sec) = explode(" ", microtime());
    return ((float)$usec + (float)$sec);
}

$time_start = microtime_float();

SOURCE CODE

$time_end = microtime_float();
$time = round($time_end - $time_start, 4);

echo "Last uncached content render took $time seconds";

In LINUX:

For one simple code:

time php -r "echo 'hello';"

output:

hello
real 0m0.095s
user 0m0.033s
sys 0m0.055s

For a php file:

time php hello.php

output:

hello
real 0m0.073s
user 0m0.025s
sys 0m0.047s

<?php
// Randomize sleeping time
usleep(mt_rand(100, 10000));

// As of PHP 5.4.0, REQUEST_TIME_FLOAT is available in the $_SERVER superglobal array.
// It contains the timestamp of the start of the request with microsecond precision.
$time = microtime(true) - $_SERVER["REQUEST_TIME_FLOAT"];

echo "Did nothing in $time seconds\n";
?>
