php恢复数组的key为数字序列的方法,数组key

本文实例讲述了php恢复数组的key为数字序列的方法。分享给大家供大家参考。具体分析如下:

这里实现php把数组的key值恢复成类似于0,1,2,3,4,5...这样的数字序列

function restore_array($arr){
 if (!is_array($arr)){ return $arr; }
 $c = 0; $new = array();
 while (list($key, $value) = each($arr)){
  if (is_array($value)){
   $new[$c] = restore_array($value);
  }
  else { $new[$c] = $value; }
  $c++;
 }
 return $new;
}
Copy after login

演示范例:
复制代码 代码如下:restore_array(array('a' => 1, 'b' => 2)); --> returns array(0 => 1, 1 => 2)

希望本文所述对大家的php程序设计有所帮助。
