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;
}

[PHP] global array
Hi,
I am running PHP 5.4 on IIs 6 on a Windows SBS 2003 server. Here is a
streamlined version of the code I am dealing with. I tried to trim as much
as possible to only show code that deals with my issue. The main issue I
think I am having is the global array statement within the function is not
working. From all of the articles I have read, I seem to be doing it
correctly, yet it does not recognize $InvReq as an array within the
function. The array works just fine outside of the function, though. Here
are the error messages:
Notice: Undefined variable: InvReq (line numbers point to inside the
function)
Warning: array_key_exists() expects parameter 2 to be array, null given
(line numbers point to inside the function)
If anyone could point out where I have incorrect syntax or something else
that would interfere with the global reference for the array within the
function, or tell me I can't do what I am doing using arrays, but assume I
don't have the ability to write to an external work table, which is why I am
trying to use an array in the first place. Thanks.

?php
$InvReq = array();
// there is some database action here and other programming, but the core
issue is writing to the array, so assume I have all of the necessary data
// data loop to gather inventory requests ---

by looping, so this check/write/update code snippet happens many times to
update/write to the array
if (array_key_exists($hldpartID, $InvReq)) {
$InvReq[$hldpartID] += $linetotal;
//if this line will create the array entry if it does not exist, then I
don't need the key_exists check, anyone??
} else {
$InvReq[$hldpartID] = $linetotal;

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
[PHP] global array, can't assign values from variables
Hi
I'm just going to give the code and output. It should be self explanatory.
The array, $criteria, is having the issue. I don't know what it's doing. I
cannot seem to assign the value from the $data variable to the
$criteria[index] value. You will see some attempts to debug the situation
which leads me to more puzzlement.
CODE:
// run when cdata is found
function characterDataHandler($parser, $data)
{
switch( $GLOBALS['currentTag'] )
{
case MINSTARTDATE : echo $data;/*$GLOBALS['criteria']['minstartdate']
= $data;*/break;
case MAXSTARTDATE : $GLOBALS['criteria']['maxstartdate'] =
junk;/*$data;*/break;
case MINSTAY : $GLOBALS['criteria']['minstay'] = $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'] = $data; break;
default: break;
}
}
echo pre\n;
print_r($criteria);
echo /pre\n;
OUTPUT:

[minstay] =

Hi
$data is not empty. It's obvious from the :

Anyways, it is overwriting itself because of begin and start tags. I didn't
realize that.

All variables in PHP are local to the scope in which it is defined. You
cannot declare a variable as global (as such). To use a global variable:
?
$doodah = 10;
test_global();
function test_global() {
global $doodah;
echo(Doodah should be ten: $doodah);
}
?
See manual for details.

This is true. But I believe that the original question was actually
the other way around... Make a local variable into a global one.
The way to do that is this:
?
myFunc() {
$myFuncLocalVar = Hello!;
echo $myFuncLocalVar;
$GLOBALS[myFuncLocalVar] = $myFuncLocalVar;
}
myFunc();
echo $myFuncLocalVar;
?
