What are the benefits of storing database queries in a separate configuration file or as stored procedures for PHP applications?

Storing database queries in a separate configuration file or as stored procedures for PHP applications can improve code organization, enhance security by preventing SQL injection attacks, and make it easier to maintain and update queries without changing the application code. 

// Example of storing database queries in a separate configuration file

// config.php
define('GET_USERS_QUERY', 'SELECT * FROM users');

// index.php
include 'config.php';

$query = GET_USERS_QUERY;
$result = $pdo->query($query);

// Example of using stored procedures

$query = $pdo->prepare("CALL get_users()");
$query->execute();
$result = $query->fetchAll();
