[PHP] break out of ?php... midway thru' an if { } statement ?
Hi everyone,
- newbie preface
-
I finally got some time to come back to learning a little more PHP...
and I am looking forward to lots more in coming months, with any
luck. Anyway, as I was working towards the last deadline with the PHP
project I was working on, I uncovered several issues I did not know
the answer to.. and I just hacked around them to avoid taking more
time while I was under the clock/meter. Now on my own time, I want to
ask, so I learn more deeply what was more ideal understanding/technique.

Here's one of those Q's:
I was working on a system (MoveableType, A.K.A. MT) that writes db
data to static text files (web pages) whenever the CMS admin tells it
to publish. That system writes out the PHP code that I tell it to,
in each page of the site. There was one place in my PHP code (marked
with ***MT***, below) where I needed to include a chunk of data that
would not be known (or written out) until the admin next published the
page (i.e. I could not include the code inline). I needed to display
it only in case of a PHP comparison evaluating to true. I was tempted
to break out of PHP at that point, and then go back into PHP within
that ***MT*** block itself, _only_ when/where in the few places that
block needs PHP.. in order to reduce the head pressure (of the less-
technical admin using the MT CMS) having to wade through so many PHP
print/echo statements (I could not get heredoc to work right, but
that is another topic/post ;-). But despite the temptation, I did not
attempt that because I thought it might break the logic of the if
{ } . On the other hand, I vaguely remember reading something that
made me think something like that is possible.. but I don't know where
I saw it.
To better summarize my Q:
could the below mt:Var name=PageMoreNoCRLF (which contains a
long block of HTML sprinkled with a little PHP whose contents are
known only at runtime) be *broken out of* of the ?php ... ? wrapper
that surrounds the if { } statement, and have it still only get
displayed on the final webpage when the if { } statement evaluates to
true? The reason I want that is so that I can just keep the HTML
straight and simple in that MT block, instead of using PHP string-
printing statements to spit out it's mostly-pure-HTML contents. The
admin using the system is using a WYSIWYG HTML editable textarea
interface, kind of like FCKEditor.
if($AlertUser2success != 0) {
echo 'div class=pg_DIVmainText'.\n;
echo 'img class=divBGgradient style= src=images/
BehindBox01.png alt= /'.\n;
echo 'div'.\n;
/*--- here is the ***MT*** block/include --- ---*/ mt:Var
name=PageMoreNoCRLF
echo '/div'.\n;
echo '/div'.\n;
} else {

If I understand the question correctly, I think the answer is yes. Maybe something like this: ?php if ($AlertUser2success): ? Normal HTML, or MT tags, here. ?php elseif ($foo == $bar): ? Normal HTML, or MT tags, here. ?php else: ? Normal HTML, or MT tags, here. ?php endif; ?

If I'm understanding the question right, yes you can.
if($AlertUser2success != 0)
{
?
div class=pg_DIVmainText
img class=divBGgradient style= src=images/BehindBox01.png alt=
/
div
?php include(); ?
/div
/div
?php
}
