Explanation

The $_GET and $_POST methods are used for retrieving data sent from an HTML form. $_GET retrieves the data by using the URL parameters while $_POST retrieves the data from form fields.

Use

The $_GET method is used when you want to retrieve data without modifying it, such as searches or sorting. The $_POST method is used when you want to modify or add data, such as creating a new user or updating an existing user.

Important Points

• The URL will contain the form data when using $_GET.
• The form data will not be visible in the URL when using $_POST.
• Always sanitize the data before using it in your code to prevent SQL injections and other security issues.

Summary

In PHP, the $_GET and $_POST methods are used for retrieving data sent from an HTML form. The $_GET method retrieves data using the URL parameters while the $_POST method retrieves the data from form fields. It is important to always sanitize the data before using it in your code.
