Use the id number as the array key and a simple loop should join

...
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,

Hi Brent,
thank you for that excellent example. I tried to get that working in a
similar way but failed. However, you brought in knowledge which puts me
into trouble. How can I output those arrays if they are the other way
around?
I used to do it like this:
for ($i=0;$i<count($result[id]);$i++){
echo $result[id][$i];
echo $result[text][$i];
}
Now the array is the other way around, plus the array
$resultSummary[$id]['id'] is not a 1,2,3 thing but there are missing
values?!
I need those Id's to create proper links from the output.
have you tried foreach? e.g.
foreach ($resultSummary as $id => $vals) {
print_r( $vals );
// do some stuff.
}
Can you shed some more light on this?
it might help to know that actually the '1,2,3 thing'
is a '0,1,2 thing' - sequential (int) keys are always zero based.
