How can the mysql dump command be used to backup a database with images?

When using the mysql dump command to backup a database with images, it's important to ensure that the images are properly included in the backup file. One way to achieve this is by using the --hex-blob option in the mysql dump command, which converts binary data (such as images) into hexadecimal format for inclusion in the backup file. This ensures that the images are preserved and can be restored along with the rest of the database.

// Backup database with images using mysql dump command
$host = 'localhost';
$user = 'username';
$password = 'password';
$database = 'dbname';
$backupFile = 'backup.sql';

// Use mysqldump command to backup database with images
exec("mysqldump --hex-blob -h $host -u $user -p$password $database > $backupFile");
