menampilkan disk space dengan php

hello...
udah lama ga nulis lagi,kali ini saya akan membahas salah satu function php yaitu disk_free_space() dan disk_total_space()

kedua fungsi ini berguna jika anda ingin mengetahui disk space pada hosting anda,berikut ini contoh penerapannya :

 php file :

<?php

/* get disk space free (in bytes) */
$df = disk_free_space("/var/www");
/* and get disk space total (in bytes)  */
$dt = disk_total_space("/var/www");
/* now we calculate the disk space used (in bytes) */
$du = $dt - $df;
/* percentage of disk used - this will be used to also set the width % of the progress bar */
$dp = sprintf('%.2f',($du / $dt) * 100);

/* and we formate the size from bytes to MB, GB, etc. */
$df = formatSize($df);
$du = formatSize($du);
$dt = formatSize($dt);

function formatSize( $bytes )
{
        $types = array( 'B', 'KB', 'MB', 'GB', 'TB' );
        for( $i = 0; $bytes >= 1024 && $i < ( count( $types ) -1 ); $bytes /= 1024, $i++ );
                return( round( $bytes, 2 ) . " " . $types[$i] );
}

?>

css file :

<style type='text/css'>

.progress {
        border: 2px solid #5E96E4;
        height: 32px;
        width: 540px;
        margin: 30px auto;
}
.progress .prgbar {
        background: #A7C6FF;
        width: <?php echo $dp; ?>%;
        position: relative;
        height: 32px;
        z-index: 999;
}
.progress .prgtext {
        color: #286692;
        text-align: center;
        font-size: 13px;
        padding: 9px 0 0;
        width: 540px;
        position: absolute;
        z-index: 1000;
}
.progress .prginfo {
        margin: 3px 0;
}

</style>

html file :

<div class='progress'>
        <div class='prgtext'><?php echo $dp; ?>% Disk Used</div>
        <div class='prgbar'></div>
        <div class='prginfo'>
                <span style='float: left;'><?php echo "$du of $dt used"; ?></span>
                <span style='float: right;'><?php echo "$df of $dt free"; ?></span>
                <span style='clear: both;'></span>
        </div>
</div>

hasil nya adalah :
