In PHP, what are the implications of using the same ID for multiple radio buttons within the same group, and how can this impact form processing and data handling?

Using the same ID for multiple radio buttons within the same group can cause issues with form processing and data handling because IDs should be unique within the HTML document. To solve this issue, you should use the "name" attribute to group radio buttons together instead of the "id" attribute. 

<form action="process_form.php" method="post">
    <input type="radio" name="gender" value="male"> Male<br>
    <input type="radio" name="gender" value="female"> Female<br>
    <input type="radio" name="gender" value="other"> Other<br>
    <input type="submit" value="Submit">
</form>
