In PHP, you can convert a GET method to a POST method by changing the method attribute of the HTML form from "get" to "post". The GET method appends form data to the URL in plain text, which can be seen by users, while the POST method sends form data in the HTTP request body, keeping it hidden from users. By changing the method attribute to "post", the form data will be securely transmitted to the server without being visible in the URL.
