The "getData" method in PHP is used to retrieve form data submitted by the user in a PHP script. This method is part of the PHP SuperGlobal array variable $_GET, which allows the retrieval of data from the URL query string.
Example 1:
If the user submits a form with the data "username=test&password=1234" using the GET method, the data can be retrieved as follows:
If the user accesses the URL http://example.com/script.php?id=12345, the value of the "id" parameter can be retrieved as follows:
$id = $_GET['id'];
This method is part of the PHP core library and does not require any additional package or library.
