PHP array Merging

Source: Internet
Author: User
There are two Arrays: {code ...} compare whether the values of Vtime in array A and Date in array B are the same. If the values are the same, merge the values (vtime, qr, Date, and Md5) into array C. If the values are different, put array A in array C. (Array A must be compared with array B. array B has only two Arrays:

===========A:array(    [0] => Array        (            [Vtime] => 2014-01-18 00:22:43            [qr] => 0a5500f5d5e5847209d83a7fe637a34f        )    [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] => 218e412b1d73f771e8b01b9d1f678f5b        )    [4] => Array        (            [Date] => 2014-01-17 00:00:00            [Md5] => 218e412b1d73f771e8b01b9d1f678f5b        ))

Compare whether the Vtime in array A is the same as the Date in array B. If the data is the same, merge (vtime, qr, Date, Md5) the data into array C,
If they are different, separate array A to array C.
(Array A must be compared with array B. array B will be retained to array C only when it corresponds to array)

Please help me find a solution.

There are two Arrays:
