What is the difference between HTML syntax for arrays and PHP syntax for arrays, and how can this difference impact data retrieval in PHP?

The main difference between HTML syntax for arrays and PHP syntax for arrays is that in HTML, arrays are represented using square brackets in the name attribute of form elements, while in PHP, arrays are accessed using square brackets after the variable name. This difference can impact data retrieval in PHP because if the HTML form elements are not named correctly using PHP syntax, PHP will not be able to retrieve the form data as an array. 

// Incorrect HTML form element naming
<form action="process.php" method="POST">
    <input type="text" name="data[]" />
    <input type="text" name="data[]" />
</form>

// Correct PHP data retrieval using array syntax
$data = $_POST['data'];
