Reading Multiple Times from PHP file Problem

Projects Interfacing w/ Software on the Computer

Hello, I am having some difficulties with reading from a php file. The code for the PHP file and the Arduino is below

PHP Code

<?php

sleep(10);
echo "Hello World";

?>

Arduino Code

#include <Ethernet.h>
  #include <SPI.h>
  
  byte mac[] = {  0x90, 0xA2, 0xDA, 0x00, 0x7E, 0xAE };
  IPAddress server(192,168,1,223);
  IPAddress ipAddress(192,168,1,224);
  IPAddress myDNS(8,8,8,8);
  IPAddress myGateway(192,168,1,1);
  IPAddress mySubnet(255,255,255,0);
  
  EthernetClient client;
  
  void setup()
  {
    Serial.begin(9600);
    Ethernet.begin(mac, ipAddress, myDNS, myGateway, mySubnet);
    
    delay(1000);
    Serial.println("connecting...");
    
    if(client.connect(server, 80))
    {
      Serial.println("Connected");
      client.println("GET /print.php");
      client.println("HTTP/1.1");
      client.println("Host: /localhost");
      client.println("user-agent: arduino/somethingorother");
      client.println();
      delay(1000);
    }
  }
  
  void loop()
  {
        
    
      if(client.available())
      {
          
          char c = client.read();
          Serial.print(c);
          delay(500);
      }
      else
      {
        Serial.println("Disconnecting");
        client.stop();
        delay(1000);
      }
      
      delay(1000);
  }

The php file waits for 10 seconds and then echos "Hello World". When I run the code in the Arduino and check the Serial Monitor I get "Disconnecting" and after 10 seconds passed I still get "Disconnecting". Now if I want the Arduino to get the updates that happened in the PHP file what do I do? Do I make multiple HTTP Requests?

Thank You

Hello, I am having some difficulties with reading from a php file.

I guess, since php is not a file format.

      client.println("GET /print.php");
      client.println("HTTP/1.1");

Wrong. The GET and the HTTP part go in the same record:

      client.println("GET /print.php HTTP/1.1");

Now if I want the Arduino to get the updates that happened in the PHP file what do I do? Do I make multiple HTTP Requests?

Of course. How else?

How is the PHP script going to change?
