Just to be picuyane:
echo isn't using the parens.
The parens are forcing PHP to evaluate the concatenation of the
strings FIRST, and then echo them.
And since the concatenation operator takes precedence over the
language construct, the parens are basically useless cruft.
not to mention that it should be written as (spaces are optional ;-)):
echo $h, "\n", $i, "\n";
which avoids any concat operation and dumps the result of each expression
direct to the buffer :-)
