[Phpwebsite-developers] php: return array of objects?

[Don S. <do...@se...>]

Came across a stumbling block and need a fresh set of eyes.

I have 3 classes in my module (among others).  Manager, Item, and Thing.  
Thing is a set of dynamic fields that could be in item.  The Thing class 
defines the fields, not their values.  So I thought it would be best to 
have my array of Things in the Manager class.

So my Manager constructor it calls the sql to get all the things out of 
the database and populates an array of Thing objects.

All is good.

Now when the Item needs to get the list of Things to display forms or 
values it would just get the list like this:

$this->mythings = $_SESSION["SES_MODULE_MANAGER"]->getThings();

Manager.getThings is defined as:

function getThings() {
	// Things is the array of Thing object populated in the 
constructor
	return $this->_things;
}

I have echo statements that verify that the array return has the same 
number of items as the array in the Manager.  However when I try to make 
function calls on the Thing objects in the array from my Item, I get error 
about call to member object on a non-object.  Example would be if I tried 
this from my Item class:

for($i=0; $i<count($this->mythings); $i++)
	$this->mythings[$i]->renderThing();


I had assumed it was pretty trivial, but can I, in fact, return an array 
of objects from the session?

I failed to note that Manager.getThings passes a reference to the Things 
array, not a copy.  Otherwise the point of keeping the Things array in the 
session would be lost.  But I have tried it with just the copy and I got 
the same error.

Nevermind.

Note to children:  When you grow up and want to be a php programmer, try 
not to be a careless idiot and re-use the variable name of your array of 
objects for an array of template data.
