I have a problem with following php-code:

<? if ($a == 1) 
	echo "a";
	if ($a == 0) {
	echo "";
} else {
	echo "b";
	}
	?>

When "$a = 0", it shows nothing.
When "$a = 1" , it shows "ab".
When "$a = 2" or above it shows "b".

What am I doing wrong, why does it show "ab", when "$a=1"

Hoping for soon answers
