trouble with echo() eval()

thesign

I created a website and loading content dynamically using PHP. The content i load can be html, php or html/php and is saved to variable $content.
My problem is, i haven't found a way yet to display all different types of documents. I can use a simple echo() for normal html and i can use eval() for php-content. But i haven't found a way yet to display html-php mix.
Do u have any idea, how to realise a script that is able to output all different contents?

thx markus

eval() should work for you... Can you give some coding examples of what you are trying to do?

hope that helps ....

$result = mysql_query($sql);
echo $result; // works with html
eval("$result"); // works with php

this is probably not the answer you want to hear but my suggestion is to re-think you whole concept here. i have always found that storing entire pages that contain both cleint-side presentation (HTML/CSS) and server-side logic (PHP/ASP) in database blobs to be a very cumbersome way to do things. You should really try and separate those two things. when i first started learning server-side scripting my first instinct was to do exactly what you seem to be trying to do and i quickly gave that up. my whole approach is to have PHP dynamically spit out chunks of client-side code instead of whole pages. these chunks when put all together create the whole page of content. i usually use a basic template document that does basic formatting of things (headers/navabars/footers) and then grab the relavent chunks of data for that page and put then in place.

if you absolutely have to do things the old way then you could grab the page out of the db, write it to a temp file and include() that file. this will parse and display all of your HTML as well as execute and expand any PHP as well. this is of course a pretty kludgy way to go but then so is eval().

just my $0.02

thanks that's exactly what i have done ... the "content" represents only chunks of the whole site. (mostly plain text)
thanks markus

eval should be able to parse html/php

you need to make sure the proper tags are in the var your
going to eval

if the var starts with html then php you need closing tag at beginning ?> of the var basicly the eval need to continue from the page that is using it and return to the page with out tag errors

another alternative is to seperate the php and html

the link here http://www.phpbuilder.com/board/showthread.php?s=&threadid=10280557

shows a example of this the example can handle html ,php or html/php
