accesing to members of objects

[julian_m]

A short piece of code which i'm having problems with:

class ClsX{

var $F_name;
var $F_array_of_obj= array();

function ClsX(&$obj, $name){
//Here I add an object reference to an array. Note that all objects
inside $F_array_of_obj will be of X class or null values
$this->F_array_of_obj[] = $obj;
$this->F_name = $name;
$this->ListParents();
}
function ListParents(){
foreach ($this->F_array_of_obj as $obj) {
echo "Te name of the parent is: ". $obj->F_name;
}
}
}//class
$clsX1 = new ClsX("","name1");

$clsX2= new ClsX($clsX1, "name2");

I thought that this code would output

"the name of the parent is name1"

but it actually prints

""the name of the parent is"

so the problem is that I can't acces to de object's data inside the
array.
Any hints?

Do you have error reporting enabled? Which version of PHP?

On 5.0.3 I get:

Fatal error: Cannot pass parameter 1 by reference in H:\temp\test.php on
line 25

This is referencing the line:

$clsX1 = new ClsX("","name1")

Which is valid - "" isn't a variable, so you can't reference it.

Well, actually I've solved the problem that I had

for ($i = 1; $i <= count($this->F_array_of_obj); $i++) {
$object = $this->F_array_of_obj[($i-1)];
$object->WhatEverObjectFunction();
}

Note that I come from a Delphi background, where all object call should
be preceded by a typecast. I mean:
TYPEOFOBJ($object)->WhatEverObjectFunction();
In this way, I'm saying "i'm sure that $object has a function named
WhatEverObjectFunction()"

BTW, What happens if $object doesn't has WhatEverObjectFunction()?

You get a run-time error and processing of the php stops.
