What potential issue could arise when using PHP sockets for server communication?

One potential issue that could arise when using PHP sockets for server communication is the lack of error handling, which can lead to unexpected behavior or crashes in your application. To solve this issue, it is important to implement proper error handling in your socket communication code to catch and handle any potential errors that may occur. 

// Create a socket
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket === false) {
    echo "Error creating socket: " . socket_strerror(socket_last_error());
    exit;
}

// Connect to the server
$result = socket_connect($socket, '127.0.0.1', 8080);
if ($result === false) {
    echo "Error connecting to server: " . socket_strerror(socket_last_error());
    exit;
}

// Send data to the server
$data = "Hello, server!";
socket_send($socket, $data, strlen($data), 0);

// Receive data from the server
socket_recv($socket, $response, 1024, 0);
echo "Server response: " . $response;

// Close the socket
socket_close($socket);
