Need help with OO PHP architecture problem

[comp.lang.php]

I can't possibly reproduce the code for this as the 2 classes in
question are about 1500 lines each and condensing is in this case
impossible due to algorithmic logic dependencies.

Let's say you have a Class A and a Class B. Let's say Class A is like
this:

class A {

var $b;

function A() {
$this->b =& new B();
}

function getOtherUniqueS tuff() {
return "this is other unique stuff";
}

function displayStuffFro mB() {
$html = $this->b->displayStuff(' isFromA');
}

}

-----------------------------------------------------------------

Basically, Class A will display stuff from a locally instantiated B
object property.

Here is class B:

class B {

function B() {}

function displayStuff($i sFromA = false) {
$html = "blah blah blah blah";
if ($isFromA) {
$html .= A::getOtherUniq ueStuff();
}
return $html;
}

}

------------------------------------------------------------------

Everything is fine and dandy, except in PHP 4.3.2 I get the following
error:

Fatal error use of undefined function getotheruniques tuff

The line that produces that error is:

$html .= A::getOtherUniq ueStuff();

This is why I need to get a better grip on OO PHP, I can't get past
this problem and have no solution, can someone please help?

Thanx
Phil

Hi Phil,

In other words, you think architecture can not work with you code. Then
why ask for help with architecture?

Your question about the example has nothing to do with architecture.
Furthermore, I happen to have php 4.3.2 running so i tried you code, but
i do not get the error. phpInfo prints this:
PHP Version 4.3.2

System Windows NT THINKPAD 5.1 build 2600
Build Date May 28 2003 15:06:05
(...)
So i am pritty damn sure this is php 4.3.2.

I added some code to my test file to make it print some things about
what your code does. This is what i get printed by my test file (viewed
as html, then copied from the browser and pasted below here):
blah blah blah blahthis is other unique stuff
NULL

a Object
(
[b] => b Object
(
)

)

I am sorry but i can't find any problem that i can help you with.

Here is the content of my test file:

<?php

class A {

var $b;

function A() {
$this->b =& new B();
}

function getOtherUniqueS tuff() {
return "this is other unique stuff";
}

function displayStuffFro mB() {
$html = $this->b->displayStuff(' isFromA');
}

}

class B {

function B() {}

function displayStuff($i sFromA = false) {
$html = "blah blah blah blah";
if ($isFromA) {
$html .= A::getOtherUniq ueStuff();
}
return $html;
}

}
$temp = new A();
print $temp->b->displayStuff(t rue);
print "<BR>\n";
print getType($temp->displayStuffFr omB());
print "<PRE>";
print_r($temp);
print "</PRE>";
?>

Thanx anyway but I got it. I just call them both statically and that
prevented some form of overinstantiati on of some kind.
