PHP is a widely used server-side scripting language that can make requests in a variety of ways. In this article, we will introduce some common PHP request methods.

1. GET request: GET request is the most common request method. Through GET requests, you can send requests to the server and get data from the server. A GET request appends data to the end of the URL, passing it to the server in the form of key-value pairs. In PHP, the $_GET global variable can be used to obtain data passed through GET requests.

2. POST request: POST request is another common request method. Unlike GET requests, POST requests place data in the body of the request rather than at the end of the URL. POST requests are typically used to submit form data to the server or upload files. In PHP, you can use the $_POST global variable to get the data passed through the POST request.

3. PUT request: PUT request is used to upload files or update resources to the server. Similar to POST requests, PUT requests place data in the body of the request. In PHP, you can use the file_get_contents("php://input") function to get the data passed through the PUT request.

4. DELETE request: DELETE request is used to delete resources from the server. Unlike GET and POST requests, DELETE requests do not return any data. In PHP, you can use the $_SERVER['REQUEST_METHOD'] variable to determine whether the current request is a DELETE request.

5. HEAD request: The HEAD request is used to obtain the same response header information as the GET request, but does not return the response body. In PHP, you can use the get_headers() function to send a HEAD request and obtain response header information.

6. OPTIONS request: The OPTIONS request is used to obtain the request methods supported by the server. In PHP, you can use the $_SERVER['REQUEST_METHOD'] variable to determine whether the current request is an OPTIONS request.

In addition to the above common request methods, PHP can also make requests through other methods, such as:

- CURL library: CURL is a powerful open source library that can be used to send various requests to the server. types of requests and obtain response data. Through the CURL library, more complex request operations can be implemented, such as setting request headers, processing redirects, etc.

- fopen function: PHP's fopen function can be used to open remote files and read their contents. Through the fopen function, a simple GET request can be implemented.

- file_get_contents function: PHP's file_get_contents function can be used to read the contents of remote files. Through the file_get_contents function, a simple GET request can be implemented.

To summarize, PHP can make requests through GET, POST, PUT, DELETE, HEAD, OPTIONS, etc. In addition, you can also use tools such as the CURL library, fopen function and file_get_contents function to perform more complex request operations. Choosing the appropriate request method depends on your specific needs and circumstances.
