Interaction between unrelated, seperate filed classes?

[genericnumber1]

Can't seem to get two classes to work together!

[b]test.class1.php[/b]:
[code]
<?php
class class1 {
public function test1(){
echo "worked!";
}
}

$class1 = new class1;
?>
[/code]

[b]test.class2.php[/b]:
[code]
<?php
class class2 {
public function test2(){
$class1->test1();
}
}

$class2 = new class2;
?>
[/code]

[b]test.php[/b]:
[code]
<?php
require_once("test.class1.php");
require_once("test.class2.php");

$class2->test2();
?>
[/code]


Running "test.php" yields:
[b]Fatal error: Call to a member function test() on a non-object in[/b] [i][filepath][/i][b]test.class2.php on line 4[/b]

Effects are the same if I define the classes in test.php as well. I'm sure it's a stupid mistake of mine, trying to do something php just doesn't like or something that just plain doesn't work.

in order to use a class you have to declare an object of that class

i.e.
$myObj1 = new class2();
$myObj1->test();

In method test2() you're using $class1 variable. $class1 variable is defined outside class2. PHP doesn't know anything about it.

[code=php:0]
<?php
class class2 {
public function test2(){
                $class1 = new class1();
$class1->test1();
}
}
[/code]

thanks! wasn't thinking about variable scope..

[code]
<?php
class class2 {
public function test2(){
$GLOBALS['class1']->test();
}
}
?>
[/code]
did the trick ;) thanks so much!
