Onomatopoeia: void and null function 'returns' in PHP

void and null function 'returns' in PHP · 22 September 2009, 16:53

<?php
function hasNoReturnValue() {
	//return null;
}
function hasNoReturnValueButReturns() {
	return /*null*/;
}
*function* returnsNull() {
	return null;
}
var_dump(hasNoReturnValue());
var_dump(hasNoReturnValueButReturns());
var_dump(returnsNull());
?>

results in

NULL NULL NULL

In case you were wondering. E_ALL reports nothing out of the ordinary, either. It’s all very well-behaved and straight-forward. Glee.
