How can PHP be used to implement a socket server for a Raspberry client?

To implement a socket server for a Raspberry client using PHP, you can create a PHP script that listens for incoming connections on a specified port. The script can then handle the incoming data and respond accordingly to the client. This allows for real-time communication between the Raspberry client and the server. 

<?php
// Create a socket server
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

// Bind the socket to a specific IP address and port
socket_bind($socket, '0.0.0.0', 8888);

// Listen for incoming connections
socket_listen($socket);

// Accept incoming connections
$client = socket_accept($socket);

// Read data from the client
$input = socket_read($client, 1024);

// Process the data
$output = "Received: " . $input;

// Send a response back to the client
socket_write($client, $output, strlen($output));

// Close the client socket
socket_close($client);

// Close the server socket
socket_close($socket);
?>
