Homephp教程PHP源码二维数组合并及去重复

$arr = array_merge($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);
