get

This code is an example of using the $_GET superglobal array in PHP to retrieve data sent in the URL as query parameters. The $_GET array is used to collect data from an HTML form using the "get" method or to retrieve data from the URL.

The code includes a link with an anchor tag that points to a file called "get.php" and includes a query parameter named "page" with a value of "1". When the user clicks on this link, it sends a GET request to the server, which includes the "page" parameter and its value.

The PHP code then uses an if statement to check if the "page" parameter is set using the isset() function. If the "page" parameter is set, the code will display its value using the $_GET array.

When the user clicks on the link, the page get.php will be loaded and the query parameter page=1 is passed to this page and the PHP script will print the value of the page variable on the page.

It is worth noting that the $_GET array is not secure and should not be used to pass sensitive data, as the data can be easily seen and modified by the user.
