Merging of PHP arrays

There are two of arrays:

===========a:array ([0] = = Array ([vtime] = 2014-01-18 00:22:43 [qr] = 0a5500f 5D5E5847209D83A7FE637A34F) [1] = = Array ([vtime] = 2014-01-17 00:00:00 [qr ] (= 218e412b1d73f771e8b01b9d1f678f5b)) ===========b:array ([0] = = Array ([Date] =            2014-01-18 00:22:43 [Md5] = 0a5500f5d5e5847209d83a7fe637a34f) [1] = = Array (        [Date] = 2014-01-18 00:22:43 [Md5] = 218e412b1d73f771e8b01b9d1f678f5b) [2] = = Array    ([Date] = 2014-01-17 00:00:00 [Md5] = 218e412b1d73f771e8b01b9d1f678f5b) [3] = = Array ([Date] = 2014-01-17 00:00:00 [MD5] = 218e412b1d73f771e8b01b9d1f678f 5b) [4] = = Array ([Date] = 2014-01-17 00:00:00 [MD5] = 218e412b1d73f77 1E8B01B9D1F678F5B))

Compares the date in the A array vtime and B arrays, and if the same data is merged (Vtime, QR, Date, Md5) into the C-array,
If they are not the same, the A array is placed separately into the C array.
(a array is compared to each of the B arrays, and b arrays are only reserved to the C array if they correspond to the A array)

Ask the master to help me think of a way.
