Hi to all,

I have multidimensional array and want find the duplicate values

Code:
array(2) {
  [1]=>
  array(3) {
    [0]=>
    string(19) "2013-02-04 02:48:00"
    [1]=>
    string(19) "2013-02-05 08:48:00"
    [2]=>
    string(19) "2013-02-06 21:48:00"
  }
  [2]=>
  array(9) {
    [0]=>
    string(19) "2013-02-04 01:48:00"
    [1]=>
    string(19) "2013-02-04 02:48:00"
    [2]=>
    string(19) "2013-02-04 22:48:00"
    [3]=>
    string(19) "2013-02-05 05:48:00"
    [4]=>
    string(19) "2013-02-05 08:48:00"
    [5]=>
    string(19) "2013-02-05 22:48:00"
    [6]=>
    string(19) "2013-02-06 02:48:00"
    [7]=>
    string(19) "2013-02-06 08:48:00"
    [8]=>
    string(19) "2013-02-06 22:48:00"
  }
  [4]=>
  array(9) {
    [0]=>
    string(19) "2013-02-04 01:48:00"
    [1]=>
    string(19) "2013-02-04 08:48:00"
    [2]=>
    string(19) "2013-02-04 22:48:00"
    [3]=>
    string(19) "2013-02-05 02:48:00"
  }
}
I have two database table for example table1 and table2

table1 has following fields
Code:
t1_ID   Start_date
table2
Code:
t2_ID   service_id  t1_ID
i want to insert the duplicate start_date once in table1 and then the id of that record in table2

For example in above array

Code:
arr[1][0]
arr[2][1]
arr[4][3]
has same start date which is 2013-02-05 02:48:00 i want to put this in table1 once like
Code:
t1_ID        start Date

1        2013-02-05 02:48:00
Now in table2
Code:
t2_ID   service_ID     t1_ID
1              1              1
2              2              1
3              4              1
Its mean in table2 subarray which has duplicate values will be inserted against it along the service id which is the index of the array which we are setting .

thanks.
