newbie question - php parsing
am 22.07.2009 22:55:47 von Sebastiano Pomata
Hi all,
A little doubt caught me while I was writing this snippet of code for
a wordpress template:
I always thought that php was called only between the tags,
and I'm pretty sure that's right, while HTML code was simply wrote in
document as is, without further logic.
Now, I can't figure out how this snippet works: I mean, shouldn't HTML
code be simply put on document, as it is outside php invoke?
Effectively if the title of page is 'Home', the HTML part is totally
skipped.
Is the if construct that does all the magic inside?

This is how I'd write this snippet
if ( 'Home' !== ( $title =3D the_title('','',FALSE)))
{
echo '
';
}
?>

I haven't used worpress in a long time, but the the_title() function
might echo the title unless you pass the FALSE parameter, in which case
it just returns it.

Not necessarily: what if you have
function the_title()
{
echo "Title";
}
for example...
In response to Sebastiano:
There would be not much point in using something like PHP if it ignored the "if"
statements in the code!
What effectively happens in a PHP source file is that all the bits outside of
the tags are treated like an "echo" statement (except that it handles
quotes and stuff nicely)
Your original code:
can be read like:
if (the_title('','',FALSE) != 'Home') {
echo '';
}
?>
You might even find a small (but probably really, really, really small)
performance improvement if you wrote it that way, especially if it was in some
kind of loop.
Note that I prefer to keep HTML separate from PHP as much as possible because it
helps me to read it and helps my editor check my syntax and HTML structure better...

Thanks, it's now much more clear. I thought that html parts outside
php tags were just dumped to output, no matter of if-else statements
and other conditions. I was *definitely* wrong
