Well, you could do it without a return, but first, addslashes() returns
the modified string, it does not do in-place replacement. And second, you
would need to pass the string in by reference, like this:
function test (& $var)
{
$var = addslashes($var)
}
$foo = "He's dreaming";
test($foo);
print($foo);
