php ???合??

1. 把一???:
[{"0":"1011","post_id":"1011","1":"4","post_parent":"4","2":"hkbc_program_name_image","meta_key":"hkbc_program_name_image","3":"50","meta_value":"50"},{"0":"1011","post_id":"1011","1":"4","post_parent":"4","2":"hkbc_program_name_special","meta_key":"hkbc_program_name_special","3":"462","meta_value":"462"},{"0":"1011","post_id":"1011","1":"4","post_parent":"4","2":"hkbc_program_ad","meta_key":"hkbc_program_ad","3":"581","meta_value":"581"},{"0":"1011","post_id":"1011","1":"4","post_parent":"4","2":"hkbc_program_ad_url","meta_key":"hkbc_program_ad_url","3":"http:\/\/music.baidu.com\/","meta_value":"http:\/\/music.baidu.com\/"},{"0":"1011","post_id":"1011","1":"4","post_parent":"4","2":"hkbc_program_sort","meta_key":"hkbc_program_sort","3":"1.1","meta_value":"1.1"},1.1"},{"0":"1009","post_id":"1009","1":"117","post_parent":"117","2":"hkbc_program_name_image","meta_key":"hkbc_program_name_image","3":"119","meta_value":"119"},{"0":"1009","post_id":"1009","1":"117","post_parent":"117","2":"hkbc_program_name_special","meta_key":"hkbc_program_name_special","3":"463","meta_value":"463"},{"0":"1009","post_id":"1009","1":"117","post_parent":"117","2":"hkbc_program_ad","meta_key":"hkbc_program_ad","3":"111","meta_value":"111"},{"0":"1009","post_id":"1009","1":"117","post_parent":"117","2":"hkbc_program_ad_url","meta_key":"hkbc_program_ad_url","3":"http:\/\/baike.baidu.com\/view\/1433405.htm","meta_value":"http:\/\/baike.baidu.com\/view\/1433405.htm"},{"0":"1009","post_id":"1009","1":"117","post_parent":"117","2":"hkbc_program_sort","meta_key":"hkbc_program_sort","3":"7","meta_value":"7"}]
?合?一??似:
[{"post_id":"1011","post_parent":"4","hkbc_program_name_image":"50","hkbc_program_name_special":"462","hkbc_program_ad":"581","hkbc_program_ad_url":"http:\/\/music.baidu.com\/","hkbc_program_sort":"1.1"},{"post_id":"1009","post_parent":"117","hkbc_program_name_image":"119","hkbc_program_name_special":"463","hkbc_program_ad":"111","hkbc_program_ad_url":"http:\/\/baike.baidu.com\/view\/1433405.htm","hkbc_program_sort":"7"}]

回复讨论(解决方案)

密密麻麻，，我都不想看 能来个简单点的例子么

[{"0":"1011","post_id":"1011","1":"4","post_parent":"4","2":"hkbc_program_name_image","meta_key":"hkbc_program_name_image","3":"50","meta_value":"50"},{"0":"1011","post_id":"1011","1":"4","post_parent":"4","2":"hkbc_program_name_special","meta_key":"hkbc_program_name_special","3":"462","meta_value":"462"}]
?合?:
[{"post_id":"1011","post_parent":"4","hkbc_program_name_image":"50","hkbc_program_name_special":"462"}]

post_id 并不只有1101,?有很多

按json读取，merge再去掉整数key？

??了,是1011.
??格式是上面的格式,??是有很多的.

按json读取，merge再去掉整数key？
?面有用源??作?目???的?

你这个数据从哪里来的，没发现生成了数字键和字符键两份了吗，如果数字键非必须的话，可以在生成的时候只生成关联数组。

按json读取，merge再去掉整数key？
你??思路是正?的,??已?解?,?了?上??.
