?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"}]

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??.
