NYCPHP Meetup

[Jeff Knight]

I recently had to move one of my php sites from one server to another 
and learned (once again) that not all php servers are the same (give me 
a break, I've had a hangover for about three days now (or is it 
four?)). One of the things that most attracted me to php after working 
with asp for so long was its lenience towards doing things on-the-fly 
without a lot of set up and declarations, etc. So I had some old code 
that worked on my 1st server:

	if ($_REQUEST['from']) {
		$from['rgb'] = $_REQUEST['from'];
	} else {
		$from['rgb'] = '000000';
	}
	if ($_REQUEST['to']) {
		$to['rgb'] = $_REQUEST['to'];
	} else {
		$to['rgb'] = 'FFFFFF';
	}
	
	echo "to: $to<BR>";
	echo "to[rgb]: {$to['rgb']}<BR>";
	
	echo "from: $from<BR>";
	echo "from[rgb]: {$from['rgb']}<BR>";

Which produced the output:
	to: Array
	to[rgb]: FFFFFF
	from: Array
	from[rgb]: 000000

When I moved the code to a new server, the results were:
	to: FFFFFF
	to[rgb]: F
	from: 4563456
	from[rgb]: 4

Of course, none of this was immediately obvious, since the code was 
inside a php script that generated a png and had no echo statements. Of 
course I should've originally said

	$from = array( 'rgb' => '000000');

But I'm lazy.

I am a little curious about what setting in php.ini allows this 
behavior on my (development) server though, since I suppose I should 
turn it off so it matches with the outside world.
