strange reference behavior

[Robert Enyedi <renyedi@xxxxxxxxx>]

Hi,

I've been studying the PHP reference mechanism (with PHP 5.2.1) and I'm 
unsure if the following behavior is normal.

This code works as expected:

	$a = 2;
	$b = &$a;
	//$c = &$a;
	$c = $b;
	$a = 1;

	echo $c."\n"; // Prints "2" as expected

but this one does not:

	$a = 2;
	$b = &$a;
	$c = &$a;
	$c = $b; // Should overwrite the previous assignment, so $c
		 // should get a copy of $b (and NOT a reference)
	$a = 1;
	
	echo $c."\n"; // I would expect "2", but prints "1"

Could anyone please clarify why this happens?

Regards,
Robert
