global var problem

[sempuritoza]

hi all

i am building something using classes and i need to create an array of objects, i have no problems doing this but the problem comes in when i try to make a counter variable to keep track of how many objects i have of this type.

i want to put the :
$counter += 1;
into my constructor function (i think this would be the best place to put it) my problem comes in with declaring the $counter variable as global, i declare all my private / class variables like this :

var $var_01;
var $var_02;
var $var_03;
var $var_04;
var $var_05;
var $var_06;
//the problem comes in here when i declare my $counter variable
global $counter;
//once i do this the pages instantiating objects of type class A dont run and as soon as i comment this out they work again.

😕 :bemused: :glare: 😕

is it a setting in the php.ini file that i need to change or am i declaring the variable as the wrong "access type"

any help will be greatly appreciated.

To find the number of objects in the array, use count() on the array.

Another way (more in line with your idea) is to implement static class variables, but that's rather messy in PHP4.

er,

I am aware of the count function but that does not do the full job of what i need, i geuss i should have explained better in my original post. sorry...

explanations are not my strong point but i will try explain it a bit better, there might come a time where i need to access array elements in the middle of the array so its not just for the purpose of keeping track of the number of elements but also to assign an internal id to each object in the array.

hope that makes a little more sense, i get the feeling i might be making more work for myself than is neccessary.

thanx for your help, AGAIN 😉 :p 😉 :p

i think i should look into this static class variables, but you said its messy?why is that?

there might come a time where i need to access array elements in the middle of the array so its not just for the purpose of keeping track of the number of elements but also to assign an internal id to each object in the array

An 'internal' id is automatically assigned to each member of a numerically indexed array.

i was not aware of this and that is exactly what i am looking for, thanx for your time.
