troopers Posted November 28, 2010 Share Posted November 28, 2010 Hey all I have an error in my Facebook application and I'm not sure what's wrong (New to PHP). The error output is: Warning: array_rand() [function.array-rand]: Second argument has to be between 1 and the number of elements in the array in /home/app/view.php on line 15 And the PHP lines are as follows: $friends = $facebook->api('/me/friends'); print_r(array_rand($friends, 3)); Link to comment https://forums.phpfreaks.com/topic/220055-error-in-my-application/ Share on other sites More sharing options...
