How to find disk space in PHP?

<?php
$bytes = disk_total_space(".");
$si_prefix = array( 'B', 'KB', 'MB', 'GB', 'TB', 'EB', 'ZB', 'YB' );
$base = 1024;
$class = min((int)log($bytes , $base) , count($si_prefix) - 1);
//echo $bytes . '<br />';
$total = sprintf('%1.2f' , $bytes / pow($base,$class)) . ' ' . $si_prefix[$class];

$bytes = disk_free_space(".");
$si_prefix = array( 'B', 'KB', 'MB', 'GB', 'TB', 'EB', 'ZB', 'YB' );
$base = 1024;
$class = min((int)log($bytes , $base) , count($si_prefix) - 1);
//echo $bytes . '<br />';
$free = sprintf('%1.2f' , $bytes / pow($base,$class)) . ' ' . $si_prefix[$class];

   $used = (float)$total-(float)$free;
echo "Total Space : $total <br/> Available Space : $free <br/> Used Space : $used ".$si_prefix[$class];
?>

Difference between two dates in PHP

<?php
$date1 = "2015-01-23 00:20";
$date2 = "2015-01-23 05:30";
$seconds = strtotime($date2) - strtotime($date1);
$days    = floor($seconds / 86400);
$hours   = floor(($seconds - ($days * 86400)) / 3600);
$minutes = floor(($seconds - ($days * 86400) - ($hours * 3600))/60);
$seconds = floor(($seconds - ($days * 86400) - ($hours * 3600) - ($minutes*60)));
echo "$days Days, $hours Hrs $minutes mins $seconds sec";
?>

Difference between two dates in Javascript with demo

Enter values in mm/dd/yy hh:mm:ss format
First date and time
Second date and time
Result
In (decimal) hours
In (decimal) minutes
In seconds

Code:
<script type='text/javascript'>

function p (i){

return Math.floor(i / 10) + "" + i % 10;

}

function trunc (i){

var j = Math.round(i * 100);

}

function calculate (form){

var date1 = new Date(form.date1.value);

alert(form.date1.value+"\n\n"+date1)

var date2 = new Date(form.date2.value);

var sec = date2.getTime() - date1.getTime();

if (isNaN(sec)){

alert("Input data is incorrect!");

return;

}

if (sec < 0){

alert("The second date ocurred earlier than the first one!");

return;

}

var second = 1000, minute = 60 * second, hour = 60 * minute, day = 24 * hour;

form.result_h.value = trunc(sec / hour);

var days = Math.floor(sec / day);

sec -= days * day;
