note 25959 added to function.uksort

I couldn't find a function anywhere to sort a 2d array, so I ported something I wrote in JavaScript. This sorts by a primary column, an optional secondary column, and in either ascending or decending order. It is, however, a little slow. If you come up with a better one, please post here and email it to me. /* sort2D - sort a two-dimensional array by a given column and direction arguments: arIn - a two-dimentional array intPrimary - the first column to sort by intSecondary - the second column to sort by (use false or an empty string to sort only by primary) boolDirection - the direction to sort (1/true = ascending, 0/false = decending) returns: a copy of arIn, sorted as specified */ function sort2D($aIn, $sPrimary, $sSecondary='', $bDirection=1) { for($i=0; $i<count($aIn); $i++) { for($j=0; $j<count($aIn); $j++) { $bSwitchRows = false; if(($bDirection) && (strcasecmp($aIn[$i][$sPrimary], $aIn[$j][$sPrimary]) < 0)) { $bSwitchRows = true; } if((!$bDirection) && (strcasecmp($aIn[$i][$sPrimary], $aIn[$j][$sPrimary]) > 0)) { $bSwitchRows = true; } if((strcasecmp($aIn[$i][$sPrimary], $aIn[$j][$sPrimary]) == 0) && ($sSecondary !== "")) { if(($bDirection) && (strcasecmp($aIn[$i][$sSecondary], $aIn[$j][$sSecondary]) < 0)) { $bSwitchRows = true; } if((!$bDirection) && (strcasecmp($aIn[$i][$sSecondary], $aIn[$j][$sSecondary]) > 0)) { $bSwitchRows = true; } } if($bSwitchRows) { $aTemp = $aIn[$j]; $aIn[$j] = $aIn[$i]; $aIn[$i] = $aTemp; } } } return($aIn); } -- http://www.php.net/manual/en/function.uksort.php http://master.php.net/manage/user-notes.php?action=edit+25959 http://master.php.net/manage/user-notes.php?action=delete+25959 http://master.php.net/manage/user-notes.php?action=reject+25959
