Move items up or down in an associative array list php -

hi want know i can move items in associative array 'up or down' 1 example array :

 array ( [list] =>        array ( [name1] => 1,                [name2] => 1,                [name3] => 1,                [name4] => 1,                [name5] => 1,  )  )  

i know how in non-associative array in way :

   $a = array('a','b','c','d','e');     function down($a,$x) {      if( count($a)-1 > $x ) {     $b = array_slice($a,0,$x,true);     $b[] = $a[$x+1];     $b[] = $a[$x];     $b += array_slice($a,$x+2,count($a),true);     return($b);      } else {              return $a;           }    }   function up($a,$x) {    if( $x > 0 , $x < count($a) ) {     $b = array_slice($a,0,($x-1),true);     $b[] = $a[$x];     $b[] = $a[$x-1];     $b += array_slice($a,($x+1),count($a),true);     return($b);    } else {              return $a;         }  }    //use     // move item 4   print_r(up($a,4)); 

try code

$array=array(0=>'name1', 1=>'name2', 2=>'name3', 3=>'name4', 4=>'name5');  function moveelement(&$array, $a, $b) {     $out = array_splice($array, $a, 1);     array_splice($array, $b, 0, $out); } moveelement($array, 3, 1);  print_r($array);  result :  array ( [0] => name1 [1] => name4 [2] => name2 [3] => name3 [4] => name5 )
