(php) if condition not working

Question

I am going crazy here. The following simple if-condition does not produce the right output.

$xxx = 1;
if($xxx == 1)
    define('DEBUG', true);
else
    define('DEBUG', false);
var_dump($xxx);
var_dump(DEBUG);
die();

Output:

int(1)
bool(false)

I see absolutely no reason why the DEBUG constant is not being set to true. PHP's type juggling should allow this if-statement. And even if I put an intval in front of the variable, it still produces false as output.

Edit 2: I copied the exact code from above into a new file and it produces the expected output. So I don't know what is going on...

the 1 in string(1) is an indication of the length of the string, not its value. try echo $vbulletin->userinfo['userid']; to see what its value actually is. — Brian Driscoll

Why don't you cast your $vbulletin->userinfo['userid'] as an int anyway? — Brad

it seems, that there is something missing in your debug output for userid: As Brian mentioned the (1) indicates the length, but usually the content follows after that. — KingCrunch

Must be some caching issue. Must be server-side. I changed the code entirely, refreshed the page (by holding down the shift key) and it still produces the old output. Happens in all browsers. — reggie

Try a var_dump on DEBUG (or print_r(get_defined_constants());) before you define it and see what the output is in both cases. It appears that you can "redefine" if one define statement includes the is_case_sensitive flag... — horatio

var_dump($vbulletin->userinfo['userid']);

Output :

string(1)

Your string length is one, and it seems to be empty (a space ?).

$vbulletin  = new stdClass();
$vbulletin->userinfo    = array('userid' =>  1);

if(1 == $vbulletin->userinfo['userid'])
    define('DEBUG', true);
else
    define('DEBUG', false);
var_dump(DEBUG);
echo "\n";
var_dump($vbulletin->userinfo['userid']);

There isn't anything wrong with your code. Running the above code gives me

bool(true) int(1)

I suspect your $vbulletin->userinfo['userid'] variable has a different value to what you think it has

EDIT

When I change it to

$vbulletin->userinfo    = array('userid' =>  '1');

I get string(1) "1". You're string appears to be empty, and that's the reason it's failing.

A var_dump of the vbulletin variable produces string(1) "1", so I don't see it.

@reggie, Try explicitly setting the value just above the condition and see. If it work then the data in your variable is off. You can focus on it next

@reggie, just to confirm, You tried setting the value explicitly just above the IF condition and it still did not evaluate properly? At this my recommendation would be to install Eclipse + Xdebug and put on your debugger hat :)

Yes, I explicitly defined the value just above the if-statement. I am a Zend certified developer, and this issue is highly stupid and annoying me to the extreme. I can't make any sense of the results. When I paste it into a separate document that contains only code above, it works. It makes no sense.

@reggie, happens to all of us. Just start up the debugger and see what's actually in there at run time.
