NYCPHP Meetup

[Phil Powell]

I'm using PHP 4.3.2 on the development server box here at work.  Sorry 
about the mistakes, I had to copy over the code by hand as there are 
firewall issues right now between the boxes, so I can't just easily punt 
the code over, but it's pretty much verbatim.  I'll try the $GLOBALS 
code instead.

For one, $q_id is an integer, while the '1' element of $question['1'] is
declared as a string.  Thus, $question[$q_id] has a cast involved, and
it might not be clear how it's being casted, thus resulting in a
associative or indexed array.  Probably not the problem, but if you're
using a number, keep it without quotes.

> echo $question[$q_id]['answer'][$val]['count']."<br>";
>=20
> $question[$q_id]['answer'][$val1]['count']=3D9999;
>=20
> echo $question[$q_id]['answer'][$val1]['count']."<br>";
>=20
> will echo back 'count' as being 8 and 9

There's a strange cast happening.  When you declare the answer element,
it's being declared as an associative array, containing and Yes and No
elements.  These Yes and No elements contain strings - not arrays.  So,

$question[$q_id]['answer'][$val]['count']=3D8888

is trying to reference the element named by $val (in this case Yes) as
an array, when it's a string.  You'd need to declare the 'answer'
element something like:

'answer'=3D>array('Yes'=3D>array('Yes',0),'No'=3D>array('No',0));

Then

$question[$q_id]['answer'][$val]['count']=3D8888;

should work as expected.  All this said, I'd rethink using this level of
multidimensional arrays  :)
