php中如何把多個數組合並為一個數組

array_merge() 函數把兩個或多個數組合並為一個數組。

如果鍵名有重復，該鍵的鍵值為最後一個鍵名對應的值（後面的覆蓋前面的）。如果數組是數字索引的，則鍵名會以連續方式重新索引。

例如：

$news=M('news');     
  $sql="select count(a.news_id) as count_news,a.menu_id,b.pid from news a left join menu b on a.menu_id=b.menu_id where a.is_pass=0 group by a.menu_id ;";  
  $count=$news->query($sql);  
  $text_check=M('text_check');  
  $sql2="select count(a.check_id) as count_news,a.menu_id,b.pid from text_check a left join menu b on a.menu_id=b.menu_id where a.is_pass=0 group by a.menu_id ;";  
  $count2=$text_check->query($sql2);  
dump($count);exit
dump($count2);exit;  
dump(array_merge($count,$count2));exit;
