Question

Following script is to create 1 lack html buttons.

<?php 
for($i=1; $i<=100000;$i++)
{
    echo "<button>".$i."</button>";
}
?>

I need to catch/record the time. At the end, the result should shows:
Script take “x” minutes, “x” seconds and “x” milliseconds. Actually I am cloning a virtual machine that takes about 4 to 5 minutes depending upon the size of the disk. So that’s why I need customized output.

Straight off PHP’s documentation:

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

$time_start = microtime_float();

for ($i = 1; $i <= 100000; $i++)
{
    echo "<button>".$i."</button>";
}

$time_end = microtime_float();
$time = $time_end - $time_start;

echo "Time taken = $time seconds\n";

I’d be extremely concerned about your hardware spec if your PHP script took minutes to execute 😉
