stream_socket_server Function synopsis

stream_socket_server(
    string $address,
    &$error_code = null,

    int $flags = STREAM_SERVER_BIND | STREAM_SERVER_LISTEN,
    $context = null
  )

Parameters

$address

Typestring

The type of socket created is determined by the transport specified using standard URL formatting: transport://target.

$error_code

Passed by reference, OptionalDefault valuenull

If the optional $error_code and $error_message arguments are present they will be set to indicate the actual system level error that occurred in the system-level socket(), bind(), and listen() calls. If the value returned in $error_code is 0 and the function returned false, it is an indication that the error occurred before the bind() call. This is most likely due to a problem initializing the socket. Note that the $error_code and $error_message arguments will always be passed by reference.
