What are some common mistakes made by PHP beginners when working with arrays in PHP forms?

One common mistake made by PHP beginners when working with arrays in PHP forms is not properly accessing array values submitted through a form. To access array values in PHP form submissions, you need to use the `$_POST` or `$_GET` superglobal arrays with the name attribute of the form input as the key. Another mistake is not checking if an array key exists before accessing it to avoid errors. 

// Example of properly accessing array values submitted through a form
if(isset($_POST['input_name'])){
    $array_value = $_POST['input_name'];
    // Use $array_value as needed
}
