array ( 0 => array ( 'id' => '10', 'title' => 'a','type' => '1', 'bian'=>'1'),
1 => array ( 'id' => '10', 'title' => 'a','type' => '1', 'bian'=>2),
2 => array ( 'id' => '11', 'title' => 'b','type' => '2', 'bian'=>'1'),
3 => array ( 'id' => '11', 'title' => 'c','type' => '2', 'bian'=>'2'),
)
当type=1去除相同id重复并且key变成ID,当type=2时KEY变成id_bian的形式,最终转成以下数组
array ( 0 => array ( '10' => '', '11_1' => '','11_2' => ''),)
然后在与下面数组合并
array ( 0 => array ( '10' => '1','11_2' => '1'),
1 => array ( '10' => '1','11_2' => '1'),
2 => array ( '11_1' => '1','11_2' => '1'),
3 => array ( '10' => '2','11_2' => '1'),
)
最终得到
array ( 0 => array ( '10' => '1','11_1'=>'','11_2' => '1'),
1 => array ( '10' => '1', '11_1 => '', 11_2' => '1'),
2 => array ( '10' => '', '11_1' => '1', '11_2' => '1'),
3 => array ( '10' => '2', '11_1' => '', '11_2' => '1'),
)
如果在$C里追加$t做为元素是不是要重新遍历?
追加 array ( '10' => '', '11_1' => '','11_2' => '')做为$c的
就是数组a整里的结果插到$c中,是不是一定要把$c在遍历一次?

不太明白你的意思

并没有遍历 $c 啊
