How can PHP handle errors related to server storage space calculations?

When dealing with errors related to server storage space calculations in PHP, you can use the `disk_free_space()` function to check the available disk space before performing any operations that involve writing or storing data. By checking the available disk space beforehand, you can prevent errors related to running out of storage space during runtime.

// Check available disk space before performing any operations
$requiredSpace = 1024 * 1024 * 10; // 10 MB
$availableSpace = disk_free_space('/path/to/directory');

if ($availableSpace < $requiredSpace) {
    die('Error: Insufficient storage space.');
}

// Proceed with the operations that involve writing or storing data
