You actually wouldn't need to have any entry for id in the resulting array since the id is the key for the array "row".
But you setup your array backwards, and you have a one multidimensional array, not three arrays. With your setup, if there is a value missing from any of the three "categories", then your data is out of sync.
Arrays are great for creating name/value pairs. But you should view a two dimensional array as a row/column setup: $result[row][column]
So your array should be setup like:
$result[0]['id']
$result[0]['text']
$result[0]['relevance']
$result[1]['id']
$result[1]['text']
$result[1]['relevance']
...
This assures your data aligns properly and it's actually easier to process in a loop.

Hi there,
I do have a tricky problem with arrays.
There are 3 arrays:
$result[id][] $result[text][] $result[relevance][]
Now there might be the case that there are more results with the same $id. I would like to count all the relevances together for the same id.
For example: id text relevance 23 ok 2 42 joel 1 23 php 1
Desired output: id text relevance 23 ok php 3 42 joel 1
Has anybody an ide how to do that?
Thank you for any help,
Merlin
