Here's a fix for this, left by a commenter on my own blog. Credit and thanks to Peter Stacey for this one:

I was having this problem on a database that was used by existing application and so couldn't change the column type. After much searching I discovered that if you store the result of the query with $stmt->store_result(); before $stmt->bind_result($var) it works!

e.g.
$stmt->execute();
$stmt->store_result();
$stmt->bind_result($content);

Yup thanks, I ended up finding that same post through Google. Changed the column to text. Low tech but it worked.

It looks like to be a bug due to mysqli:

I love this class but for some reason I can't select data from a longtext field. I can see the data in phpmyadmin, but when I select it using the class and echo the variable in the array, I get blank space. Any ideas?

I'm trying to do something similar right now. Unfortunately your class lacks a facility to pass parameters to the SQL. I started with PHP this afternoon, so I'm probably still stupid regarding PHP, but how about adding a second parameter to q, say an associative array, then use mysqli_STMT:bind_param() to add the parameters to the statement before executing it?

@Cuke:
1) It returns false when there is an error. So you can do:

$result = $db->q('...');
if (!$result) { Error() }

2) An object is automatically passed as reference, no need to add another one on top of it.

3) Free the returned array !? PHP has a garbage collector, the array will be freed as soon as you don't use it anymore.

@Timo:
Yeah, extending the mysqli object is a good idea. I didn't think about it when writing it.

Whenever I run this I get
Number of elements in type definition string doesn't match number of bind variables
from the line

call_user_func_array(array($query, 'bind_param'), $args_ref);

Doesn't bind_param have to be told what type each var that is passed is supposed to be? like string, integer, etc..
