重组数组 - PHP 重组二维数组-PHP中文网问答

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：
