calling a function of an object returned by a function

CrashRoX

I end up getting a parse error when i try to call the function of the object returned by the function. Any suggestions?

<?php
	class class1 {
		var $hello = new class2();

	function myFunc() {
		return $hello;		
	}

}


class class2 {

	function displayStuff() {
		echo "stuff";
	}

}


$test = new class1();
$test->myFunc()->displayStuff();

?>

Hmm... I messed around with your code a bit. I'm not an expert at classes... perhaps one of these classes 'extends' the other?

Take a look at this page from PHP's Manual, perhaps?

Sorry I couldn't help.

$test->myFunc()->displayStuff();

You can't call the method directly in php4. You first have to assign the return value of myFunc() to a variable and then call your method on that. Coming from java that annoyed me at first. (This does work in php5 though.)

var $hello = new class2();

I doubt that works. You can only assign constant values to class properties here. This should be in the constructor instead.

return $hello;

I think you meant $this->hello.

Yea, thats was I thought. But I assumed there had to be a way to do it all on one line. The work around was assign it to a local temp variable. You COULD access the class variable directly, and that works. But thats not good programming as far as classes go. But thank you for you help. Glad they added it in PHP5.
