What is the significance of the query string in PHP and how can it be accessed?

The query string in PHP is used to pass data from one page to another through the URL. This data is typically in the form of key-value pairs and can be accessed using the $_GET superglobal array in PHP. To access the query string parameters, you can use $_GET['key'] to retrieve the value associated with a specific key.
