php数组遍历类与用法示例

<?php
  class scanArray{
    public $arr;
    public $where;
    private $str;
    public function scan($arr,$where="array"){
      $this- arr = $arr;
      $this- where = $where;
      foreach($this- arr as $k= $v){
        if(is_array($v)){
          $this- where = ($this- where)."[{$k}]";
          $this- scan($v,$this- where);
        }else{
          $this- str .= $this- where."[{$k}]=".$v.'<br / ';
        }
      }
      return $this- str;
    }
    function __destruct(){
      unset($this- arr);
      unset($this- where);
    }
  }
  $a = array('g'= "a",'vv'= array("b"= "b","l"= "c","xx"= array("e","g")));
  $ah = new scanArray();
  $b = $ah- scan($a);
  echo $b;
