problem with array of objects

[necron]

I am working for the first time with classes in PHP and I am stuck with a result that I don't understand: I am trying to print out the value of a variable of an object that is stored in an array of objects, but for some reason what it prints is: "Array[0]- >myContent".

Here the details:

1. I have got objects of the class "Level" that each have got a variable called $myContent (holds some kind if text-string).

2. One of my classes (DropArea) is adding objects of the class "Level" to an array, so I made a function for it:

//Class DropArea
var $allPrimaryLevels;
function addLevel($levelObject)
{
$this->allPrimaryLevels[count($this->allPrimaryLevels)]=$levelObject;
}

3. The class DropArea is meant to print out the value of $myContent of every Level object it has stored in its array. It does this by printing the following line (I am looping through the array using a for-loop):

print("$this->allPrimaryLevels[$i]->myContent");

But for some reason, the above line prints instead of the content of $myContent: "Array[0]->myContent"

I am assuming I must go wrong with the calling of the functions somewhere, but I can't figure out where?

Thanks for the help, guys!

I see two problems above, the first may be intentional, but I don't think so.

1) This code is just reassigning $levelObject to $this->allPrimaryLevels[0], rather than adding another position to the array:

var $allPrimaryLevels;
function addLevel($levelObject)
{
$this->allPrimaryLevels[count($this->allPrimaryLevels)]=$levelObject;
} 

It looks like you're trying to assign $levelObject to count()+1 but have forgotten the '+1' ... if that's the case, you can just do:

var $allPrimaryLevels;
function addLevel($levelObject)
{
$this->allPrimaryLevels[]=$levelObject;
} 

2) Because you're using double quotes, php is trying to parse the string. Instead of the above code, use:

print($this->allPrimaryLevels[$i]->myContent);

Ooopps. Please scrap the first half of my post above. I forgot about the offset in the array.

But, I'd still recommend using:

$array[] = 'next val';

rather than:

$array[count($array)] = 'next val';

The second way is a little slow since it has to count each time.
