I'm trying to make a web page that can query a game server for call of duty 2, i seem to get issues with create a socket_create() im using php 8.3 the error i get is:
Fatal error: Uncaught TypeError: socket_set_timeout(): Argument #1 ($stream) must be of type resource, Socket given in E:\laragon\www\index.php:19 Stack trace: #0 E:\laragon\www\index.php(19): socket_set_timeout(Object(Socket), 2) #1 E:\laragon\www\index.php(100): getServerInfo('116.203.79.194', '28960') #2 {main} thrown in E:\laragon\www\index.php on line 19
this is line 13 causing the error
socket_set_timeout($socket, 2);full code can anyone tell me what im doing wrong to understand this error please.
