本文实例讲述了php数组遍历类与用法。分享给大家供大家参考,具体如下:

<?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;

运行结果:

array[g]=a
array[vv][b]=b
array[vv][l]=c
array[vv][xx][0]=e
array[vv][xx][1]=g
