How to retrieve the request type of an input value in PHP?

To determine the request type of the input value in PHP, you can use the $_SERVER[‘REQUEST_METHOD’] variable. This variable contains the current HTTP method of the request, such as GET, POST, PUT, or DELETE. Here is an example:

if ($_SERVER['REQUEST_METHOD'] == 'GET') {
    echo '请求类型是GET';
} else if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    echo '请求类型是POST';
} else {
    echo '其他请求类型';
}

By checking the value of $_SERVER[‘REQUEST_METHOD’], you can determine the type of the current request and perform the necessary operation accordingly.
