What are the potential pitfalls of assigning a name to a submit button in PHP forms?

Assigning a name to a submit button in PHP forms can potentially cause issues when processing the form data, as the name attribute will be included in the form data sent to the server. This can lead to unexpected behavior or errors when trying to access the form data in PHP. To avoid this issue, it is recommended to not assign a name to the submit button in PHP forms. 

<form method="post" action="">
    <input type="text" name="username" placeholder="Username">
    <input type="password" name="password" placeholder="Password">
    <input type="submit" value="Submit">
</form>
