How can one determine the amount of storage space occupied and remaining on a web hosting package using PHP?

To determine the amount of storage space occupied and remaining on a web hosting package using PHP, you can use the disk_total_space() and disk_free_space() functions. These functions will return the total disk space and free disk space in bytes respectively. You can then calculate the used space by subtracting the free space from the total space.

$total_space = disk_total_space('/');
$free_space = disk_free_space('/');
$used_space = $total_space - $free_space;

echo "Total Space: " . round($total_space / (1024*1024*1024), 2) . " GB<br>";
echo "Used Space: " . round($used_space / (1024*1024*1024), 2) . " GB<br>";
echo "Free Space: " . round($free_space / (1024*1024*1024), 2) . " GB";
