Array Help

[mickjav]

Managed to sort Arrays with one value but multidimensional Arrays are giving me a headache

I would like to add rec_id and artist to an array then I was thinking of using Array_search to get the artist if there if one but even my books are not helping me?

Code Select Expand

//Get A List If Singles For The Combi Array
$Recsquery = $smcFunc['db_query']('', '
SELECT  ar.rec_id, COALESCE(a.artist_the, a.artist_name) As Artist
FROM {db_prefix}art_and_rec AS ar
INNER JOIN {db_prefix}artists AS a ON (ar.art_id = a.art_id)
WHERE ar.main = 1 AND ar.rec_id IN(SELECT rec_id from {db_prefix}art_and_rec WHERE art_id = ' . $art . ')');

while ($recrow = $smcFunc['db_fetch_assoc']($Recsquery))
$recrow[] = $recrow['rec_id'];
Any help would be much appreciated

All the best mick

Um, why not sort it in the database query and be done with it?

do you mead ASC OR DESC

This is lookup for a artist "A Combination of Artists" which my db uses

It's being uses here

I have found something I thought I could understand

Code Select Expand

//Get A List If Singles For The Combi Array
$Recsquery = $smcFunc['db_query']('', '
SELECT  ar.rec_id, COALESCE(a.artist_the, a.artist_name) As Artist
FROM {db_prefix}art_and_rec AS ar
INNER JOIN {db_prefix}artists AS a ON (ar.art_id = a.art_id)
WHERE ar.main = 1 AND ar.rec_id IN(SELECT rec_id from {db_prefix}art_and_rec WHERE art_id = ' . $art . ')');

if ($smcFunc['db_affected_rows']() != 0)
{
while ($recrow = $smcFunc['db_fetch_assoc']($Recsquery))
{
$arrrow = array(
array('ID' => $recrow['rec_id'],
  'Art' => $recrow['Artist']),
  );
}
}
$smcFunc['db_free_result']($Recsquery);
And to get the artist I tried this:
$key = array_search($rec, array_column($arrrow, 'art'));

But it's still not returning the artist even though I know the queries retuning records

You know that you can sort the query by multiple columns in both ascending and descending order, right?

array_search finds a value in an array, it's about the most inefficient way possible to ever do sorting. In any case, array_search doesn't tell you the value it found, it tells you the array index where it found it, which is of... zero use to you as far as I can see.

The problem with what you're doing is that I can only see what you've done, I have no ability to make sense of what you're *trying* to do, if I'm honest it's usually why I avoid most of these threads.

I could do what I want but it would cost in number of queries used as I could convert the above to something I can use in_array with then call a function with a query that could return the value I want but as I said it's would be costly in queries run.

If you think it would help I could post the function??
