How can PHP arrays affect the functionality of JavaScript in a form submission?

When PHP arrays are used to store form data, the keys of the array can affect how the data is accessed and processed in JavaScript during form submission. To ensure that JavaScript can correctly handle the form data, it is important to use consistent naming conventions for the array keys in PHP and access them properly in JavaScript. 

<form method="post" action="process_form.php">
    <input type="text" name="user[name]" />
    <input type="email" name="user[email]" />
    <input type="submit" value="Submit" />
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $userData = $_POST['user'];
    // Process form data
}
?>
