What is the correct way to define a textarea in a PHP form to ensure it functions as intended?

When defining a textarea in a PHP form, it is important to use the correct syntax to ensure it functions as intended. The textarea element should have a name attribute to identify it when the form is submitted, and the content of the textarea should be placed between the opening and closing textarea tags. Additionally, the rows and cols attributes can be used to specify the size of the textarea.

<textarea name="message" rows="4" cols="50"></textarea>
