I hear one area you are going to run into trouble is your dotted column
names. you will need to use AS to rename the columns before you can use
them like $row['answer'] and such. here's why:
C:\Documents and Settings\Jim>php test1.php
Array
(
[0] => 1
[cat_id] => 1
[1] => a
[category] => a
[2] => 1
)
C:\Documents and Settings\Jim>type test1.php
<?php
mysql_connect("localhost","username","password");
mysql_select_db("database");
$q=mysql_query("SELECT * FROM categories,categoryroots WHERE
categories.cat_id=categoryroots.cat_id") or die("oops1.");
$row=mysql_fetch_array($q);
print_r($row);
mysql_free_result($q);
?>
C:\Documents and Settings\Jim>
well, I got everything from the categories table (trhe first table mentioned
in the SELECT). Because I didn't specify the columns I wanted from both
tables.
