NULL and empty are both not same

null is not equal to '' or '' empty in PHP 

$nulltest='';
if($nulltest==null){
	echo "i am null";
}


it will print "i am null"
but it is not empty string and null is same
lets check value and type with === , 


$emptytest='';
if($emptytest===null){
	echo "i am null";
}

now with checking with ===, it shows nothing, because empty string and null is not the same
