One array is sorted by another array.

{Code...} known $ a. Sort $ B into $ c by referring to $.

$ A = Array ('cid' => 1, 'cname' => 'about'), Array ('cid' => 7, 'cname' => 'Introduction'), Array ('cid' => 8, 'cname' => 'cultural '), Array ('cid' => 9, 'cname' => 'dynamic '); $ B = Array ('cid' => 1, 'cname' =>' '), array ('cid' => 2, 'cname' => 'Opera '), Array ('cid' => 3, 'cname' => 'meiju '), array ('cid' => 4, 'cname' => 'video'), Array ('cid' => 5, 'cname' => 'enter '), array ('cid' => 6, 'cname' => 'contacts '), Array ('cid' => 7, 'cname' => 'Introduction '), array ('cid' => 8, 'cname' => 'cultural '), Array ('cid' => 9, 'cname' => 'dynamic ')); $ c = Array ('cid' => 1, 'cname' => 'about'), Array ('cid' => 7, 'cname' => 'Introduction'), Array ('cid' => 8, 'cname' => 'cultural '), Array ('cid' => 9, 'cname' => 'dynamic '), Array ('cid' => 2, 'cname' => 'Opera'), Array ('cid' => 3, 'cname' => 'meiju '), Array ('cid' => 4, 'cname' => 'video'), Array ('cid' => 5, 'cname' => 'enter'), Array ('cid' => 6, 'cname' => 'Contact '));

$ A is known, and $ B is sorted into $ c by reference to $.

Use the custom sorting function usort.

  ref = $ref;   $this->array = $array;          usort($this->array,function($t1,$t2){        $p1 = array_search($t1,$this->ref);        $p2 = array_search($t2,$this->ref);        if(($p1===false||$p1===null) && ($p2===false||$p2===null))          return array_search($t1,$this->array)array) ? -1 :1;        if($p1===$p2) return 0;          if($p1===false||$p1===null) return 1;        if($p2===false||$p2===null) return -1;         return $p1<$p2 ? -1 : 1;      });    } }//----------------------$res = new SortByArray($a,$b);print_r($res->array);?>

This should be a multi-dimensional array Sorting Problem. array_multisort in php can be used for multi-dimensional array sorting.
The specific implementation code will not be written. You can take a look at the manual.

/*** [The oneArrayTo two-dimensional array sorts one-to-multiple objects by an array value] * @ param [type] $ a [reference array] * @ param [type] $ B [This is sorted array] * @ param [type] $ keyword [key value] * @ return [type] [description] */function oneArrayTo ($, $ B, $ keyword) {$ newa = array (); foreach ($ a as $ key = >$ value) {$ newa [] = $ value [$ keyword];} $ newa = array_flip ($ newa); $ newb = array (); foreach ($ B as $ key => $ value) {$ newb [] = $ value [$ keyword];} $ newb = array_flip ($ newb); $ d = $ newb; foreach ($ newb as $ k = >$ v) {foreach ($ newa as $ key = >$ value) {if ($ key = $ k) {unset ($ d [$ k]) ;}}$ c = array_flip ($ newa); $ d = array_flip ($ d); $ p = array_merge ($ c, $ d); $ p = array_flip ($ p); $ newbb = array (); foreach ($ B as $ key => $ value) {$ newbb [$ value [$ keyword] = $ value;} $ g = array (); foreach ($ p as $ key => $ value) {$ g [] = $ newbb [$ key];} return $ g ;}

I wrote it myself, though stupid.
