PHP切割多维数组

Question

任何人都可以帮助我的功能或指向我切割多维数组的方向?

这是我需要的:

$array[x][y][b][q][o][p];
$array[b][c][f][q][l][v];
$newArray = cut_array_depth($array, 2);
// Would return a new array with a maximum dimension of 2 elements
// all others would be left out
$newArray[][];

谢谢,

你可以自己写解决方案(即使我不太理解'切割'逻辑)

<?php
function cut_array_depth($array, $depth, $currDepth = 0){
    if($currDepth > $dept){
        return null;  
    }
   $returnArray = array();
   foreach( $array as $key => $value ){        
      if( is_array( $value ) ){              
          $returnArray[$key] = cut_array_depth($value, $depth , $currDepth +1);
      } else {
          $returnArray[$key] = $value;
   }
   return $returnArray;
}
?>
