Hi,
This is the first time I've REALLY tackled multi-dimensional arrays, in
conjunctions with functions.
I like the way this code works:
<?
$sql = "select from....";
$result = mysql_result($sql);
while($myrow = mysql_fetch_array($result))
{
echo $myrow['colname'];
}
?>
So I built a function which returns a multi-dimensional array:
<?
function getSongByArtist($artist_id,$order='title ASC')
{
$sql = "
SELECT *
FROM songs
WHERE artist_id='{$artist_id}'
ORDER BY {$order}
";
$result = mysql_query($sql);
if(!$result)
{
return 0;
}
else
{
while($myrow = mysql_fetch_array($result))
{
foreach($myrow as $k => $v)
{ $$k = $v; }
$songs["$id"] = array(
'title' => "$title",
'writers' => "$writers",
'video' => "$video",
'artist_id' => "$artist_id"
);
}
return $songs;
}
}
?>
I can then do:
<?
$songs = getSongByArtist(4);
print_r($song);
?>
... and it prints the results I'm expecting. All good.
However, I was hoping to use it in a similar way that I use mysql in the
above code... something like:
<?
while($song = getSongByArtist(4))
{
echo song['title'];
echo song['writers'];
echo song['video'];
echo song['artist_id'];
}
?>
But it's just running through an infinite loop. Perhaps mysql_fetch_array()
is doing something magic??? Perhaps I need to return something different in
my function?
I guess I could do it as a foreach()...
