How can using an array in $GLOBALS[] be a faster and easier alternative to fetching configuration settings from a MySQL database in PHP?

Fetching configuration settings from a MySQL database in PHP can be slower and more resource-intensive compared to using an array in $GLOBALS[]. By storing configuration settings in an array within the $GLOBALS[] superglobal, you can easily access them throughout your PHP application without the need to query the database each time. This can lead to faster and more efficient execution of your code. 

// Storing configuration settings in $GLOBALS[] array
$GLOBALS['config'] = [
    'db_host' => 'localhost',
    'db_user' => 'root',
    'db_pass' => 'password',
    'db_name' => 'database'
];

// Accessing configuration settings
echo $GLOBALS['config']['db_host']; // Output: localhost
echo $GLOBALS['config']['db_user']; // Output: root
echo $GLOBALS['config']['db_pass']; // Output: password
echo $GLOBALS['config']['db_name']; // Output: database
