What is the correct order of functions (create -> bind -> connect) when working with PHP sockets to avoid errors like [10049] Die angeforderte Adresse ist in diesem Kontext ung�ltig?

When working with PHP sockets, it is important to follow the correct order of functions to avoid errors like [10049] Die angeforderte Adresse ist in diesem Kontext ungültig, which translates to "The requested address is invalid in this context." The correct order of functions when working with PHP sockets is to first create the socket using socket_create(), then bind the socket to a specific address and port using socket_bind(), and finally connect the socket to the remote address using socket_connect(). Following this order will ensure that the socket is properly set up and connected without any errors.

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

// Bind the socket to a specific address and port
if (!socket_bind($socket, '127.0.0.1', 8080)) {
    echo "Failed to bind socket: " . socket_strerror(socket_last_error($socket));
}

// Connect the socket to the remote address
if (!socket_connect($socket, '127.0.0.1', 80)) {
    echo "Failed to connect socket: " . socket_strerror(socket_last_error($socket));
}
