What are some common mistakes that PHP beginners make when working with arrays in form submissions?

One common mistake that PHP beginners make when working with arrays in form submissions is not properly accessing the array values. When receiving form data as an array, it's important to use the correct array key to access the submitted values. Another mistake is not checking if the array key exists before accessing it, which can lead to errors if the key is not present in the submitted data. 

// Example of properly accessing array values in form submissions
if(isset($_POST['my_array'])) {
    $myArray = $_POST['my_array'];
    
    // Accessing specific array values
    $value1 = $myArray['key1'];
    $value2 = $myArray['key2'];
    
    // Use the values as needed
}
