如何将原二维数组重组成以下形式？
原数组
Array
(
[0] => Array
(
[第1-2节] =>
[第3-4节] => Web网站开发与维护_每周_XXXX_01-15周_S1-205
[第5-6节] => Linux高级应用_每周_XXXX_01-15周_A-910
[第7-8节] => 网络安全_每双周_XXXX_01-15周_A-507
[第9-10节] =>
)
[1] => Array
(
[第1-2节] => IPV6技术_每周_XXXX_01-14周_S1-303
[第3-4节] =>
[第5-6节] => 网络安全_每周_XXXX_01-15周_C-408
[第7-8节] =>
[第9-10节] =>
)
[2] => Array
(
[第1-2节] => 网络营销_每周_XXXX_01-14周_C-201
[第3-4节] =>
[第5-6节] => 就业指导_每周_XXXX_11-12周_B-202
[第7-8节] =>
[第9-10节] =>
)
[3] => Array
(
[第1-2节] => Linux高级应用_每单周_XXXX_01-15周_A-910/Web网站开发与维护_每双周_张劲波_01-15周_A-910
[第3-4节] =>
[第5-6节] => Cisco高级应用_每周_XXXX_01-14周_S1-305
[第7-8节] => Linux高级应用_每周_XXXX_01-15周_S1-303
[第9-10节] =>
)
[4] => Array
(
[第1-2节] => 网络安全_每周_XXXX_01-15周_A-508
[第3-4节] => Web网站开发与维护_每周_XXXX_01-15周_A-908
[第5-6节] =>
[第7-8节] =>
[第9-10节] =>
)
)
重组后的格式为：
Array
(
[0] => Array
(
[第1-2节] =>
[第1-2节] => IPV6技术_每周_XXXX_01-14周_S1-303
[第1-2节] => 网络营销_每周_XXXX_01-14周_C-201
[第1-2节] => Linux高级应用_每单周_XXXX_01-15周_A-910/Web网站开发与维护_每双周_XXXX_01-15周_A-910
[第1-2节] => 网络安全_每周_XXXX_01-15周_A-508
)
[1] => Array
(
[第3-4节] => Web网站开发与维护_每周_XXXX_01-15周_S1-205
[第3-4节] =>
[第3-4节] =>
[第3-4节] =>
[第3-4节] => Web网站开发与维护_每周_XXXX_01-15周_A-908
)
[2] => Array
(
[第5-6节] => Linux高级应用_每周_XXXX_01-15周_A-910
[第5-6节] => 网络安全_每周_XXXX_01-15周_C-408
[第5-6节] => 就业指导_每周_XXXX_11-12周_B-202
[第5-6节] => Cisco高级应用_每周_XXXX_01-14周_S1-305
[第5-6节] =>
)
[3] => Array
(
[第7-8节] => 网络安全_每双周_XXXX_01-15周_A-507
[第7-8节] =>
[第7-8节] =>
[第7-8节] => Linux高级应用_每周_XXXX_01-15周_S1-303
[第7-8节] =>
)
[4] => Array
(
[第9-10节] =>
[第9-10节] =>
[第9-10节] =>
[第9-10节] =>
[第9-10节] =>
)
)
[1] => Array
(
[第3-4节] => Web网站开发与维护_每周_XXXX_01-15周_S1-205
[第3-4节] =>
[第3-4节] =>
[第3-4节] =>
[第3-4节] => Web网站开发与维护_每周_XXXX_01-15周_A-908
)
这种key相同的写法，后面的key会覆盖前面的，你应该是期望得到这种结果：
[第1-2节] => Array
(
[0] =>
[1] => IPV6技术_每周_XXXX_01-14周_S1-303
[2] => 网络营销_每周_XXXX_01-14周_C-201
[3] => Linux高级应用_每单周_XXXX_01-15周_A-910/Web网站开发与维护_每双周_XXXX_01-15周_A-910
[4] => 网络安全_每周_XXXX_01-15周_A-508
)
[第3-4节] => Array
(
[0] => Web网站开发与维护_每周_XXXX_01-15周_S1-205
[1] =>
[2] =>
[3] =>
[4] => Web网站开发与维护_每周_XXXX_01-15周_A-908
)
可以写一个function：
public function listData($arr){
if(empty($arr)) return array();
$listData = array();
foreach($arr as $key=>$value){
foreach($value as $k=>$v){
$listData[$k][] = $v;
}
}
return $listData;
}
测试数组
$arr = array(
0=>array(
'a'=>1,
'b'=>2,
'c'=>3,
),
1=>array(
'a'=>11,
'b'=>22,
'c'=>33,
),
2=>array(
'a'=>111,
'b'=>222,
'c'=>333,
),
);
得到：
array
'a' =>
array
0 => int 1
1 => int 11
2 => int 111
'b' =>
array
0 => int 2
1 => int 22
2 => int 222
'c' =>
array
0 => int 3
1 => int 33
2 => int 333
