In PHP, $_GET is a superglobal variable used to retrieve variables passed through the GET method. It can be used to access the values of parameters passed by users through the URL.

For example, if the URL that the user accesses is:

http://example.com/index.php?id=123&name=John

You can use $_GET to retrieve the values of id and name:

$id = $_GET['id']; // 123
$name = $_GET['name']; // John

It is important to note that values obtained using $_GET are passed as strings, so conversion may be necessary depending on the situation. Additionally, variables obtained through $_GET are passed through the URL, so security precautions should be taken to prevent malicious exploitation.
