本文实例讲述了php二维数组合并及去重复的方法。分享给大家供大家参考。具体实现方法如下:

$arr = array_merge($labels,$label);
//合并需要合并的俩个数组
  $key = id;//去重条件
  $tmp_arr = array();//声明数组
 foreach($arr as $k => $v)
 {
  if(in_array($v[$key], $tmp_arr))
//搜索$v[$key]是否在$tmp_arr数组中存在,若存在返回true
  {
   unset($arr[$k]);
   //删除掉数组($arr)里相同ID的数组
  }
 else {
   $tmp_arr[] = $v[$key];
   //记录已有的id
  }
 }
dump($arr);

希望本文所述对大家的php程序设计有所帮助。
