I really think you are overthinking this!
If you want to echo out "<?php echo('FOO'); ?> for instance and have the
preprocessor parse it... you need to (dangerously) eval it ....
$variable="<?php echo('<p>foo</p>'); ?>";
eval($variable);
....... "<p>foo</p>" is returned to the browser...
So (and i highly do not recommend this unless you truely trust the text in
your database and the files it is opening) u must use php's eval();
Like so ... (using your variables)
eval($retstr);
then anything inside that variable or file will be evall'd as opcode and
passed through the pre-processor and you will be left with html or whatever
your php code spits out!

Subject: [Proto-Scripty] Re: php in files
Ok, let me put my idea to you and see if there is a way without
reloading the whole page -
I use prototype.js and project.js. project.js is just my entensions
for each project, which I have narrowed down to two functions, -
function myRequest( text ) {
new Ajax.Request('requests.php',
{
method: 'post',
postBody: text,
onComplete: myResponse
});
}
function myResponse(req) {
$(targetdiv).innerHTML= req.responseText;
}
Where text is supplied from the controls, such as 'page=home'.
request.php is the only php file called directly, it decides which
response is wanted and returns the text for a control or entire body
for <div id='mainbody'></div>
All of my pages and controls within them are created in php from the
database. This is very easy to maintain and update, so a nice base for
all kinds of applications
All works well if I only respond with html including the ajax side
that recalls requests.php, the only problem is that I intended some of
the pages to be applications, so I want them to have php and can not
see a way to pass it through the preprocessor.
My request.php at the server side is like this -
$Home=$button=$update=$testButton=$menuItem="";
extract($_POST,EXTR_IF_EXISTS);
if($menuItem != "")
{
$retstr = "";
$dbconn = getdbconnection();
//find page associated with this menu item
$query = 'SELECT body FROM menu WHERE name=\''.$menuItem.'\'';
$result = pg_query($dbconn,$query) or die('Query failed: ' .
pg_last_error());
$row = pg_fetch_row($result);
//read in the file
if(file_exists($row[0]))
{
$handle = fopen($row[0],"r");
$retstr = fread($handle,filesize($row[0]));
fclose($handle);
//failed attempt to use include instead
//$retstr = "<?php include ".$row[0]."; ?>";
}
else
{
$retstr = "File not created yet";
}
pg_close($dbconn);
echo $retstr;
}
In the end this would leave me with only one main page index.php and
all other pages called up via ajax and created or loaded via php.
I have the feeling now that I have to update the whole page, not a
terrible tragedy, but I just have the feeling that I can somehow put
my fread() file through the php preprocessor.
