note 86193 added to function.return

As obvious as it may seem, it might still be useful to point out that return called without any value returns null.

<?php
function test() {
  return;
}
print gettype(test()) . "\n";
print (test()?'true':'false') . "\n";
print (!test()?'true':'false') . "\n";
print (test() === false?'true':'false') . "\n";
?>

This returns:

NULL
false
true
false
