Note Submitter: tarnishedniteNOSPA(T)MgMAIL ---- While bob's sort is nice I found that this one was a little more to my liking. This little library ignores case and sorts on multiple criteria with some fairly short and simple code. I'm sure it could be simplified further - switch statement perhaps. <?php /*Scoped global*/ $LDAPSortOrder; /*$array is the return from ldap_get_entries $sortBy is an array of values to sort by in the order in which to sort them $reverse will sort in reverse order if true */ function LDAPSort(&$array,$sortBy,$reverse=FALSE){ global $LDAPSortOrder; $LDAPSortOrder = $sortBy; if($reverse){ usort($array,'ldapcomparereverse'); } else { usort($array,'ldapcompare'); } } /* The compare functions always check case insensitive*/ function ldapcompare($x,$y){ global $LDAPSortOrder; /* Loops through the items in order until a difference is found */ foreach($LDAPSortOrder as $ele){ if(strtolower($x[$ele][0]) == strtolower($y[$ele][0])) continue; elseif(strtolower($x[$ele][0]) < strtolower($y[$ele][0])) return -1; else return 1; } return 0; } /*Just like above but in reverse order*/ function ldapcomparereverse($x,$y){ global $LDAPSortOrder; foreach($LDAPSortOrder as $ele){ if(strtolower($x[$ele][0]) == strtolower($y[$ele][0])) continue; elseif(strtolower($x[$ele][0]) < strtolower($y[$ele][0])) return 1; else return -1; } return 0; } ?> JML
