What are the best practices for handling large database backups in PHP applications?

Handling large database backups in PHP applications can be challenging due to memory limitations and execution time constraints. One way to address this issue is to use the mysqldump command-line utility to export the database in chunks and save them to separate files. This approach helps to avoid memory overflow and allows for better management of large backups. 

<?php

// Define database connection parameters
$host = 'localhost';
$username = 'root';
$password = 'password';
$database = 'my_database';

// Define backup directory
$backupDir = '/path/to/backup/directory/';

// Execute mysqldump command to export database in chunks
exec("mysqldump --opt -h {$host} -u {$username} -p{$password} {$database} > {$backupDir}backup.sql");

?>
