How can PHP developers ensure independence and flexibility in their code by using arrays for parameter mappings in function calls?

To ensure independence and flexibility in their code, PHP developers can use arrays for parameter mappings in function calls. By using arrays, developers can easily change the order of parameters or add/remove parameters without affecting the function calls. This approach also makes the code more readable and maintainable.

function exampleFunction($params) {
    $param1 = $params['param1'];
    $param2 = $params['param2'];
    
    // Function logic using $param1 and $param2
}

// Function call with parameter mapping using arrays
$params = [
    'param1' => 'value1',
    'param2' => 'value2'
];
exampleFunction($params);
