Question

Is there way to return a two dimensional array from a SQL query? Like..

“SELECT id, x, y, z FROM test”

..and have it return as id => x, y, z? I could do a loop and create a second array but I imagine that’s extra work that I might not have to do. Just not familiar with SQL right now.

In PHP, SQL queries will only return result sets. Rows and columns.

You need a further loop in order to process it into an array of the kind that you are referring to. That’s no problem, and should be part of your database wrapper if you use it frequently.

$result = mysql_query(...);
$aData = array();
while($row = mysql_fetch_assoc($result))
   $aData[$row['id']] = array($row['x'], $row['y'], $row['z']);
