Spaces would affect sorting if the spaces appeared in the actual rowID data. If rowID is stored as
text of some kind, then yeah, maybe he'd have an issue. But I have a feeling you're
talking about the code itself and whether to put the quer into a variable or not (rebuting what I
said).
Here's his code:
> $table_name ='users';
> $result = mysql_query("SELECT * FROM $table_name ORDER BY rowID DESC");
Code looks fine. $table_name gets substituted for it's value, 'users'. There are
no extra spaces in the variable data. Even if there was, that's fine. If it were something
like this, he'd have a problem:
> $result = mysql_query("SELECT * FROM
$table_name ORDER BY
> rowID DESC");
Then it would look for a table named <space>users. Which probably doesn't exist.
Also.. that doesn't relate to the sorting issue since sorting is on 'rowID' within
that table, which isn't defined in a variable, but stated explicitly in the query.
So not sure what you're saying about spaces messing things up.

Well, if you have blank spaces on the field's beginning it won't sort
correctly, it will put the blank spaces on the last results on that case.
