The $_GET Variable

The predefined $_GET variable is used to collect values in a form with method="get"

Information sent from a form with the GET method is visible to everyone (it will be displayed in the browser's address bar) and has limits on the amount of information to send.

Example


Name:
Age:

When the user clicks the "Submit" button, the URL sent to the server could look something like this:

The "welcome.php" file can now use the $_GET variable to collect form data (the names of the form fields will automatically be the keys in the $_GET array):

Welcome .

You are years old!

 


When to use method="get"?

When using method="get" in HTML forms, all variable names and values are displayed in the URL.
