How can PHP developers effectively use arrays to store and iterate through form elements to reduce redundancy in their code?

To effectively use arrays to store and iterate through form elements in PHP, developers can create associative arrays where the keys correspond to the form element names and the values represent the form data. By doing this, developers can reduce redundancy in their code by looping through the array to process the form data instead of writing repetitive code for each form element. 

// Example of storing form elements in an associative array and iterating through them
$form_data = [
    'name' => $_POST['name'],
    'email' => $_POST['email'],
    'message' => $_POST['message']
];

foreach ($form_data as $key => $value) {
    // Process each form element here
    echo $key . ': ' . $value . '<br>';
}
