1) I've never found the <? code ?> text <? code ?> method to be all that
much faster. And I find it makes code quite ugly to read. I use the <?=
syntax in small templates quite often.
example:
file1 >> $foo = 'bar'; include('file2');
file2 >> <?=$foo;?>
2) single quotes are much faster than double quotes and I have huge scripts
which show a noticable difference.
example:
file1 >>print 'foo '.$bar.' baz';
is faster than
file1 >>print "foo $bar baz";
3) For long HTML dumps in php I often either use a template system but if
it's just a one time thing I use the <<< syntax which isn't meant for speed
but makes code easy to read.
example:
print <<<EOF
<html>
<body>
<strong>blah</strong>
</body>
</html>
EOF;
4) This is offtopic but for people who don't know -- The ternary operator is
a HUGE save in terms of time and code readability. It offers no speed
increase however. (it isn't slower though)
example:
if ($foo) {
foo_is_true($foo);
} else {
foo_is_false($foo);
}
TURNS INTO:
(($foo) ? foo_is_true($foo) : foo_is_false($foo));
5) Last offtopic comment. -- If you are ever planning on making an
application support multiple languages it is a good idea to begin writing
strings as using the gettext() methods. This will allow you to change the
applications lanaguage at anytime without rewriting your code. It does
offer a speed hit though, so decide if you need it.
example:
file1 >> print _('my text'); // gettext() shorthand
INSTEAD OF
file1 >> print ('my text'); // inflexible but fast way
Hope that helps and then some,
