which personally I think is ugly and a waste of space ;-)
(actually I used to do it like that but the better I got at programming
the more I found myself trying to condense my code - mostly so that I
could fit more of it on screen.)
currently I reserve the above CS for functions and classes.
e.g.
myCoolFunc( $arg1, $arg2 = 'default' )
{
// do something cool!
}

this is my (exact) preference for block statements.
its all very personal this!

which very quickly gets completely unreadable when the complexity starts
piling up.

much easier to read, but what about:
<?php
echo 'blahh1>test</h1>blah';
?>
or (where the literal strings would normally be vars):
<?php
echo 'blah','h1>test</h1>','blah';
?>
or (the semi-colon can be dropped here):
<?= 'blahh1>test</h1>blah'; ?>
the consensus is (AFAIKT) that the less you break in and out of PHP
the more legible your code is likely to be. In the same vein it is often
suggested to first process/gather you data and then output everything
after your script is done doing its thing, rather than echoing as you go.
there is also the HEREDOC style of echoing output (actually its a method
of string delimitation) e.g.:
<?
echo <<< THE_END
yadda yadda yadda $myArr['key1'][$key2]
$jumpup, $howhigh
THE_END;
?>

I always advise that readability/maintainability is king - speed is
hardly ever an issue on an average php site, and when speed becomes
critical optimizing echo statements is probably not where you want to
start (creating objects and calling functions is way,way heavier).
so in short: do what you find to be the easiest to read back in 6 months
time!
