worked for two days trying to figure that one out. Anyway, for future

know if the '+=' statement will create an array entry if one doesn't exist?
If you are using a higher loglevel, you'll get a notice for a not existing array
key.
In the othercase
$array[$mykey] += 1;
will work without notice. But as the key does not exist, the value will be null
and right now I am not sure what
null + 1
evaluates to?
Well, works
maro@marco-behnke:~$ php -a
Interactive shell
php $array = array();
php $array['foo'] += 1;
PHP Notice: Undefined index: foo in php shell code on line 1
PHP Stack trace:
PHP 1. {main}() php shell code:0
php var_dump($array);
array(1) {
[foo]=
int(1)
}
BUT I stronly recommend not to do that.
make it this way:
$array[$mykey] = array_key_exists($mykey, $array) ? $array[$mykey] += 1 :
$array[$mykey] = 1;
or better:
if (array_key_exists($mykey, $array)) {
$array[$mykey] += 1;
} else {
$array[$mykey] = 1;
}

And much better is adding it as another parameter and inject it:
function Part_BOM($PartID, $need, $phase, $InvReq) {
}
// call it
Part_BOM(..., ..., ..., $InvReq);
And please read about foreach() and what you can do with it.

Yes - PHP is very picky. Hence I never capitalize anything! I use underscores to make varnames more understandable, as in $inv_req -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I think he means camelCase naming syntax. It does tend to involve fewer keystrokes and results in shorter names that might more easily fit to a screen or paper, but I have to say I prefer the underscore convention, it just makes things much more readable (which is probably why built-in PHP functions and constants use it) -- Thanks, Ash http://www.ashleysheridan.co.uk
Re: [PHP] global array
See - I didn't even notice he used camel-case - I thought he typed the same thing that got the OP in trouble. See how difficult that custom is? That's why for any case sensitive syntax, I stick to all lower case to avoid just that kind of bug-a-boo. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] global array, can't assign values from variables SOLVED
Hi
$data is not empty. It's obvious from the :
OUTPUT:
9/6/2003
Anyways, it is overwriting itself because of begin and start tags. I didn't
realize that.
Thanks.

This code can't be clearly evaluated, There are several things that
can be wrong
CODE:
switch( $GLOBALS['currentTag'] )
{
case MINSTARTDATE : echo $data;/*$GLOBALS['criteria']['minstartdate']
= $data;*/break;
case MAXSTARTDATE : $GLOBALS['criteria']['maxstartdate'] =
junk;/*$data;*/break;

case MAXSTAY : $GLOBALS['criteria']['maxstay'] = $data; break;
case MINRENT : $GLOBALS['criteria']['minrent'] = $data; break;
case MAXRENT : $GLOBALS['criteria']['maxrent'] = $data; break;
case RENTINC : $GLOBALS['criteria']['rentinc'] = $data; break;
case MINBEDS : $GLOBALS['criteria']['minbeds'] = $data; break;
case MAXBEDS : $GLOBALS['criteria']['maxbeds'] = $data; break;
case PROPCOUNT : $GLOBALS['criteria']['propcount'] = $data; break;
default: break;
}
global $currentTag may be:
not assigned
not all uppercase
have a leading or trailing space
not be one of the 'case' values
$data is empty.
