How can the socket_read() function in PHP lead to endless loops and how can this be prevented?

The socket_read() function in PHP can lead to endless loops if the socket connection is not closed properly. To prevent this, you can check if the socket_read() function returns an empty string, which indicates that the connection has been closed. By adding this check, you can break out of the loop when the connection is closed. 

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

while(true){
    $data = socket_read($socket, 1024);
    
    if($data === ''){
        break;
    }
    
    // Process the received data
}

socket_close($socket);
