How to implement ip proxy server in php

php method to implement ip proxy server: 1. Create a proxy server object and initialize the proxy server, read the configuration file and set the relevant properties of the proxy server object; 2. Write an HTTP request handler to receive user requests Proxy server request and send it to the target server; 3. Create an integrated proxy server parser to automatically resolve the address and port of the target server; 4. Create an integrated IP address parser to handle the communication between the proxy server and the target server ; 5. In the proxy server, create an API calling program.

Operating system for this tutorial: Windows 10 system, php8.1.3 version, Dell G3 computer.

The technologies required to achieve this task mainly include: PHP proxy server script, HTTP request handler, proxy server parser, IP address parser and API calling program. Among them, the proxy server script is used to initialize the server object and determine how HTTP requests are processed. The HTTP request handler is used to receive user requests and access the target website; the proxy server resolver allows the proxy server to automatically identify the target server and resolve the correct IP address. The IP address resolver is used to process the proxy server. Communication with the target server; finally, the API caller can be used with other network service interfaces to assist users in using IP proxy servers.

Implementing a PHP proxy server requires the following steps:

1. First, you need to create a proxy server object and initialize the proxy server. The proxy server object stores the basic configuration of the proxy server, such as the proxy server's IP address and API calling program. In this step, we need to read the configuration file and set the properties related to the proxy server object.

2. Next, you need to write an HTTP request handler. The HTTP request handler is mainly used to receive user requests to the proxy server and send these requests to the target server. In this step, we need to create a PHP script and set the script's input to HTTP data in order to properly handle the user's request.

3. In the HTTP request handler, the proxy server parser needs to be integrated. The proxy server resolver can automatically resolve the address and port of the target server to allow for correct communication between the proxy server and the target server. A proxy server resolver usually consists of a URL parser and a program connector.

4. In the HTTP request handler, the IP address resolution program also needs to be integrated. The IP address resolver handles communication between the proxy server and the target server, as well as backing up and restoring data. IP address resolvers can provide in-depth understanding of the protocol specifications between the proxy server and the target server to quickly locate and solve problems when they occur.

5. Finally, in the proxy server, the API caller needs to be created. The API caller can make the proxy server more intelligent. Users can call the proxy server through the API and generate more complex requests. The API calling program usually contains a calling function and some supporting functions, which are used to implement the functions of the proxy server.
