php within dhtml, is that possible?

[Jacques Jamain]

hello,
in a dhtml page generated from php I want to include a file which is
in fact the body of the dhtml page. My hosting ISP does not allow SSI
but supports php includes. In the dhtml page, the generated statment
<?php include('fspecs') ?>
is ignored. I've the feeling that I'm overlooking something in the
way php is parsing dhtml (if it does). The dhtml code saved in a file
execute correctly after that...
Any hints about this?
Thanks in advance.

Jacques,

What do you mean "ignored"?

Have you looked at the source for the page when it gets to your browser?
Perhaps it's there and you don't see it.

Otherwise, you must be getting an error which isn't being displayed. Turn on
all errors and display them to see if there are any.

What do you mean, generated statement? Is 'fspecs' a file, and do you
already include it while sending the page to the browser? How do you
generate it?

The server side php can perform actions on the server, and output data to
browsers. With a few exceptions, it doesn't really care about what data,
that's your job as programmer. Sending HTML or JS is equal to sending pdf or
txt, it's just data... No checking for validity, no parsing.

PHP can't be executed on the clients machine, so if you generate <?php
include('fspecs') ?> with javascript, it's just nonsense to your browser.
So, building client side PHP code has no use, except when sending it back to
the server and eval() it, which is a huge security risk.

If it's generated on the server: echoing <?php //something ?> will not
execute it, look at eval().

If it's generated on the clients machine: look at javascipts
XHTMLhttprequest() instead.

If it's genuine PHP code on the server: what is the surrounding code, and
where does the file 'fspecs' reside?

yes, the <?php include('fspecs') ?> statment is there, well generated

ok, I have to explain a bit more what I intend to obtain.
At server side I generate an html file to include some data obtained
from mysql, to be passed to JS. This is done by echoing the html head
and the JS directives and the data with php. It's ok, and now I have
to add the html body and I was thinking that instead of echoing all
the html directives it would be nice to include a file holding all
those directives. That's SSI, but helas my hosting isp does not support,
hence the tentative with php.
The actual question: "is recursion possible with php and if yes how?"

Hope this clarify a few my situation.
Thanks for your help and suggestions.

I still don't really get what you are trying to do:
You have some data retrieved from the database, and after that you want a
HTML body...
Why not just end parsing with php (?>), and write the HTML? Echoing is nog
necessary. I think I'm missing something here.

The HTML body, is it dynamic, and if so, how do you control that: php or
client side js?

Am I to understand that a simple:
include("your/desired/file.html");
does not work?

No, PHP is never processed client-side. So if you're trying to add it inline,
i.e. with echo, it won't work.

Several ways you can do this. You can use a template processor. You can use
eval to execute the code (my personal least favorite). You can write it to a
temporary file then include the file. And probably several other ways.

But why generate the statement in the first place? Why not just execute the
statement instead?

Jacques,

PHP should parse the contents of any file with a .php extension - even if it's
referenced by include(). So if you include('xyz.php') and in that file have
include('fspecs'), it should be processed just fine.

And btw - this isn't recursion.

well, think to a quiz. At the server the Q&A are in mysql. The client
invokes that quiz as www.mysite.com. At mysite there is an index.php
which read the db, and build a dhtml set with all the things, JS data,
JS source and html body allowing to call the JS functions presenting
the quiz to the client and handling its answers. The data, the JS and
the html body are on the server. There is no problem echoing the data
and the html head directives including the JS source. My problem is to
include the html body file using php code in the index.php.
The interesting effect is that, if I save the dhtml echoed with the
<?php include('fspecs') ?> inside at client side and then I transfer
that file as is to the server I get exactly what I want.

If SSI was enabled the method would be to echo:
<!-- #include virtual=\"fspecs\" -->
instead

am I doing something wrong?
thanks

What if you replace this:

<?php include('fspecs') ?>

with this:

<?php phpinfo(); ?>

What file extension does your primary page have? If your web server
isn't setup to parse .html files for php code, the code will pass
through to the client browser without any interpretation. So if on the
client-side you are seeing "<?php include('fspecs') ?>" when you view
the page source, then I suspect you need to modify your web server's
config to parse html files for php code.

I can't do anything to the config of my isp server but on my test
machine, which is an apache server (all in one, client and server on
the same machine), the server is well configured to parse php
code (addtype, addoutputfilter, includes...). The problem is that if the
dhtml echoed by php contains php directives (<?php include('fspecs') ?>)
these directives are not parsed again by php... Anyway I think it's
not possible and I changed my design (if any d;-) and have set the db
ouput for JS in a file from a separate run and all the includes are made
from a static html file.
Thanks for your help.

any extension, .php .htm .shtml ...
to clarify you can cut and paste to your server the following
and thanks to the kindness of your browser about html standards
you would see what I mean...
__________________________________________________ _____________________
<?php echo ' <html><head> <title>Hello</title></head>' . "\n";
$fdhtml= 'fn.php';
$finc = 'inc.php';
if (!$handle=fopen($fdhtml,'w+')){echo "Can't open file ($dhtml)";exit;}

$htmStuff =
'<body><h1>Hello</h1></body></html>'. "\n";
$incStuff =
'<?php include(\'fn.php\') ?><body><h1>Hello</h1></body></html>'. "\n";
if (fwrite($handle, $htmStuff) === FALSE)
{ echo "Cannot write to file ($fdhtml)"; exit;}

{ echo "Cannot write to file ($finc)"; exit;}
fclose($handle); fclose($handle_i);
$inc = "<?php include('fn.php') ?><br>...include not included<br>";
echo $inc;
echo '<br><a href=fn.php>fn</a>';
echo '<br><a href=inc.php>inc</a><br>';
?>
__________________________________________________ _____________________

This write 2 files: fn.php and inc.php, echo an approximative dhtml and
intend to include on the fly fn.php, well echoed but not processed as
indicated in the title and in the rendered html.
In the dhtml, links to fn.php and inc.php are provided.
The link to inc.php shows that the php include is working on that server
when statically invoked...
If you are too far of your server you can try this link:

Of course it isn't included. You're sending the <?php...?> to the client.
The client can't do anything with it.

yes, I know that, but my point is (was after a bypass) "is it possible
to have a php directive like <?php include('fn.php') ?> processed on
the server within a php execution?". Now, my answer is "no, php does
not allow self recursion", but I don't want to be alone to think that
and I don't have obtained a clear answer to that question here until

Yes it is:

Call this file "foo.php", save it to your server and visit it:

<?php
global $foocount;
$foocount++;
print "This file has been included recursively $foocount times<br>\n";
if ($foocount < 100)
