How does the concept of persistent connections in MySQL relate to storing resources in PHP?

Persistent connections in MySQL allow PHP scripts to reuse database connections instead of opening and closing them for each query, which can improve performance by reducing the overhead of establishing new connections. This concept is related to storing resources in PHP because it helps optimize the usage of database connections, ensuring that resources are managed efficiently and not wasted on unnecessary connection overhead. 

// Enable persistent connections in PHP when connecting to MySQL
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = mysqli_connect($servername, $username, $password, $dbname, null, '/path/to/mysql/socket');
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}
