Concat:
$content .=3D $select[artist_name].",";
In the current code you keep overwriting $concat with the new value.
If you db object returns an array, this would be simpler:
$content =3D implode(',',$selects);
Now, all this code will not help you if an artists name contains a comma=
, =
all your logic is lost.
For creating CSV's, I'd use this:
header("Content-Disposition: attachment; filename=3Dexport.csv");
$selectSql =3D "SELECT artist_name FROM lounge_products";
$selects =3D $db->getAll($selectSql);
$out =3D fopen('php://output','w');
foreach($selects as $select) fputcsv($out,$select);
Alternatively, use mysql's built in option to export a file, which would=
=
also take care of escaping:
$file =3D '/path/to/file';
mysql_query("SELECT artist_name
INTO OUTFILE '{$file}'
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '\"'
LINES TERMINATED BY '\n'
FROM lounge_products");
header("Content-Disposition: attachment; filename=3Dexport.csv");
readfile($file);
