I'm trying to install a PHP script on my server but keep getting an error...

[08-Sep-2014 15:13:32 UTC] PHP Strict Standards: Only variables should be passed by reference in /public_html/server/websocket.class.php on line 30

[08-Sep-2014 15:13:32 UTC] PHP Strict Standards: Only variables should be passed by reference in public_html/server/websocket.class.php on line 30

Code on line 30: socket_select($changed, $write = NULL, $except = NULL, NULL);

Can anyone help?

you need to pass variables:

$write = NULL;
$except = NULL; 

socket_select($changed, $write, $except, NULL);

as socket_select() takes references as parameters

this is because expression $write = NULL passes result to function which is NULL not $write

  • I tried this and still had no luck... :/ Would you mind if I sent you the file and you had a look at it? Upload it to my Dropbox for you? – ashbridge Sep 08 '14 at 15:48
