Is there a way to combine each element of a multidimensional array with another array in php?

I have a multidimensional array which is a set of exploded numbers .ie

3-4-7
2-5-1
1-2-3
They have been exploded using "-" delimiter to input into  a database using a form that I copy and paste the numbers from a spreadsheet. I can load them individually or as a set. just fine. However I need put them into the database combined with another array  of letters ie:

Column 1          Column2
A                          347
B                          251
C                          123

The letters array are the name of tables in the database and the numbers are being inserted with each number a different field. Again I can explode and load them fine, but I want to be able to take the letter array, and copy the numbers into the form and have the numbers load into the database based on the names in the letter array. Any ideas would be appreciated.

It looks like you have two arrays there - you can use an iterator like foreach() to walk the arrays.

It would probably be helpful to see your CREATE TABLE statements and a little "before-and-after" example.

This shows how the iterators work.
foreach ($column1 as $key => $table_name)
{
    echo $column2[$key];
}

Thanks for the reply.

The table names  in the db are A, B, C  and in each table the fields are: id, date, number_1, number_2 ,number_3.

I take numbers from a spreadsheet  and copy them into a text box  like so

1-2-3
4-5-6
7-8-9 ect  
up to 20 rows of numbers. My script will explode  those number delimiting on the "-"  and upload each number into the proper fiield, but I first must select each table, then copy/paste into form then hit submit to upload. I have to do each table separately. I am looking to have an array with the each table name, and when i copy the numbers, have each row be associated with each element of the array (table name) ie

table A  matched with first pasted number 1-2-3
table B with second 4-5-6 and so on.

This looks like it could benefit from a lot of automation.  Instead of cutting numbers from a spreadsheet and pasting into a text box, try writing the spreadsheet output into a file.  You can probably save the spreadsheet as a ".csv" file.  Then when you read the spreadsheet in with fgetcsv() you will have an array of numbers (corresponding to the cells of the spreadsheet).  You can store the first row into table A, the second into table B, etc.

I have never used  fgetcsv(), so you have sent me down a new path that may the a very easy solution to all the code I have written. Thx I will let you know  shortly!

This helps a lot, but leads to another question. Does not solve issue.

Yeah, the reason it does not solve the issue is because you have not given EE adequate test data. Take some time to learn about "TDD" -- it will make your work much easier.
