What is the potential issue with using numbers as names for form elements in PHP?

Using numbers as names for form elements in PHP can lead to conflicts or unexpected behavior when trying to access those elements in the $_POST or $_GET arrays. This is because PHP automatically converts numeric form element names into arrays, which can make it difficult to access the values. To solve this issue, it's recommended to use alphanumeric names for form elements to avoid any conflicts. 

<form method="post">
    <input type="text" name="username" />
    <input type="submit" value="Submit" />
</form>
