Frequently, you want parts of your hack to only be accessible by moderators and admins.

To do so, you use this if-block:
PHP Code:
if ($bbuserinfo['usergroupid'] == 5 or $bbuserinfo['usergroupid'] == 6 or $bbuserinfo['usergroupid'] == 7) {
  /* Do stuff */
} else {
  /* Access denied */
}
And if you want to give another usergroup access for that action, you need to add even another OR to that statement!

A much more elegant solution would be to use in_array():
PHP Code:
if (in_array($bbuserinfo['usergroupid'], array(5, 6, 7))) {
You can even declare an array, let's say $allowedgroups, that can be used throughout the code:
PHP Code:
/* Earlier... */
$allowedgroups = array(5, 6, 7);

/* Somewhere in your code */
if (in_array($bbuserinfo['usergroupid'], $allowedgroups)) {
  /* Do stuff */
} else {
  /* Access denied */
}
This is also not only useable when checking usergroups! Let's say you have feature you only want visible on forums 4, 6, 18 and 65:
PHP Code:
/* Earlier... */
$specialforums = array(5, 6, 7);

/* Somewhere in your code */
if (in_array($forumid, $specialforums)) {
  /* Make use of the feature */
}
Not really a tip nor a trick, but I'm a bit bored so...

Firefly, that's good, but for performance you should really use a switch as this would prevent the test of an array, convert to an array and loop through array stuff that happens partly implicitly...

try something like...

PHP Code:
switch ($bbuserinfo['usergroupid']) {
  case 5:
  case 6:
  case 7:
    // Do stuff for usergroups 5 or 6 or 7
    break;
  case 2:
    // Do stuff for usergroup 2
    break;
  default:
    // Do stuff for everyone else
}
Just an improvement. Doesn't change functionality... but under strain this should shine.
