Two arrays, one SQL insert

[eluser]Kemik[/eluser]
Hey guys,

I've got two arrays, one called descriptions and one called prices, both have the same number of entries.

I want to insert a new row into the database for each of the array entries.

E.g.
Descriptions array

[0] => item 1
[1] => item 2
[2] => item 3

Prices array

[0] => 9.95
[1] => 12.20
[2] => 10.00

Psuedo query

Foreach (entry) {
Insert into invoices ($descriptions, $prices)
}

Would generate

Insert into invoices ('item 1', '9.95')
Insert into invoices ('item 2', '12.20')
Insert into invoices ('item 3', '10.00')

How do I take those two arrays and basically merge them in to one so I can do the foreach?

Thanks
