How can one ensure that PHP does not prematurely read the socket before receiving a response from the server?

To ensure that PHP does not prematurely read the socket before receiving a response from the server, you can use the `socket_set_blocking` function to set the socket to non-blocking mode. This will allow PHP to wait for a response from the server before attempting to read from the socket. 

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_connect($socket, '127.0.0.1', 8080);

// Set the socket to non-blocking mode
socket_set_nonblock($socket);

// Send data to the server
socket_write($socket, 'Hello server!');

// Wait for a response from the server
$response = '';
while (($data = @socket_read($socket, 1024)) !== false) {
    $response .= $data;
}

echo $response;

socket_close($socket);
