How to reorganize the original two-dimensional array into the following form?

Original array

Array ([0] = = Array ([1–2 section] = [3–4 section] + Web site development and Maintenance _ weekly _xxxx_01-15 week _s1-205 [第5-6 festival] =&gt ;    Linux Advanced Application _ weekly _xxxx_01-15 week _a-910 [7–8 Festival] + network Security _ every bi-weekly _xxxx_01-15 weeks _a-507 [第9-10 Festival] and [1] = = Array ([1–2 Festival] = IPV6 Technology _ weekly _xxxx_01-14 week _s1-303 [3–4 festival] [第5-6 Festival] and network security _ weekly _xxxx_01-15 week _c-40        8 [7–8] = [第9-10] = [2] = = Array ([1–2 section] + Network Marketing _ weekly _xxxx_01-14 week _c-201 [3–4 Festival] = [第5-6 Festival] = Employment Guidance _ weekly _XXXX_11-12 week _b-202 [7–8 festival] = [第9-10 Festival] = = [3] =&G T         Array ([1–2 section] + Linux advanced application _ every week _xxxx_01-15 weeks _a-910/web website development and Maintenance _ every two weeks _ Zhang Jingpo _01-15 week _a-910 [3–4 Festival] = [第5-6 Festival] + Cisco Advanced Applications _ Weekly _XXXX_01-14 week _s1-305 [7–8 section] + Linux Advanced application _ weekly _xxxx_01-15 week _s1-303 [第9-10 festival] =&gt     ;        ) [4] = = Array ([1–2 section] + network security _ weekly _xxxx_01-15 week _a-508 [3–4 section] + Web site development and Maintenance _ weekly _xxxx_01-15 Week _a-908 [第5-6 Festival] = [7–8] = [第9-10] =)) 

The

Format after reorganization is:

Array ([0] = = Array ([1–2 section] = [1–2 section] + IPV6 technology _ weekly _xxxx_01-14 week _s1-303 [1–2 festival] = Network Marketing _ Weekly _xxxx_01-14 week _c-201 [1–2 festival] + Linux Advanced application _ every week _xxxx_01-15 weeks _a-910/web website development and Maintenance _ every bi-weekly _xxxx_01-15 weeks _a-910 [1–2 Section] + Network security _ weekly _xxxx_01-15 week _a-508) [1] = = Array ([3–4 section] + Web site development and Maintenance _ weekly _xxxx_01-15 Week _s1-205 [ 3–4 [3–4] = [3–4 festival] + [3–4 Festival] + Web site development and Maintenance _ weekly _xxxx_01-15 week _a-908) [2] =&G T Array ([第5-6 section] + Linux Advanced application _ weekly _xxxx_01-15 week _a-910 [第5-6 section] + network security _ weekly _xxxx_01-15 week _c-408 [第5-6 Section] = Employment Guide _ weekly _xxxx_11-12 week _b-202 [第5-6 Festival] + Cisco Advanced Applications _ Weekly _xxxx_01-14 weeks _s1-305 [第5-6 Festival] = [3] =&gt ; Array ([7–8 section] + network security _ _xxxx_01-15 Week _a-507 [7–8 section] [7–8 festival] = [7–8 Festival] =&gt ; Linux Advanced Application _ weekly _xxxx_01-15 week _s1-303 [7–8 festival] + = [4] = = Array ([第9-10 section] = [第9-10 Festival] =&gt         ; [第9-10 Festival] = [第9-10] = [第9-10] =)) 

[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    )

This key is the same way of writing, the following key will overwrite the previous, you should be expected to get this result:

[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    )

Can write a 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;    }

Test array

$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,    ),);

Get:

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
