Problems with arrays

[eluser]Perkin5[/eluser]
Now I've just tried this:

Code:

$actual_price;
foreach ($records as $item):
foreach ($price as $code){
$var1 = $code->cat;
$var2 = $item->price;
$var3 = $code->val;
if($var1 == $var2){
$actual_price = $var3;
}
}
...
endforeach;

and amazingly it works, so presumably CI didn't like me putting $code->cat etc inside an if statement.

Not sure I understand what has happened.
