This article mainly introduces the method of socket communication between php and python. It analyzes related operation skills such as php using custom classes to send socket request data and Python to receive socket data and process requests in the form of examples. Friends who need it can Refer to the following

The example of this article describes how to implement socket communication between php and python. Share it with everyone for your reference, the details are as follows:

Design purpose

Initiate a request through the front-end page and hand it over to php, and php will create a socket request and hand it over to the Python script, and then after execution is completed, return to the front end.

#index.html

<html>
<head>
  <title>test</title>
  <script>
  g_xmlHttpReq = new XMLHttpRequest();
  function onReplyCallback()
  {
    if(g_xmlHttpReq.readyState==4 && g_xmlHttpReq.status==200)
    {
      alert(g_xmlHttpReq.responseText);
    }
  }
  function on_stop_service()
  {
    g_xmlHttpReq.open("GET","./service/main.php?cmd=1",true);
    g_xmlHttpReq.onreadystatechange=onReplyCallback;
    g_xmlHttpReq.send(null);
  }
  </script>
</head>
<body>
<button onclick="on_stop_service()">关闭服务</button>
</body>

# Now, you can use telnet to test it, the command is "telnet 127.0.0.1 9011"
# You also can use web broswer to test, input the address of "http://127.0.0.1:9011" and press Enter button
