What role does safe_mode play in causing issues with dba_open() in PHP?

Safe_mode in PHP can cause issues with dba_open() because it restricts access to certain files and directories, which may prevent the function from opening the specified database file. To solve this issue, you can disable safe_mode in your PHP configuration or use a different method to access the database file that is allowed under safe_mode.

// Disable safe_mode in PHP configuration
ini_set('safe_mode', 0);

// Use an alternative method to access the database file
$db = dba_open('/path/to/database', 'c', 'dbm');
