retrieving php code from database and have it translate

[franco714]

im trying to retrieve a php code ( something like <?php echo bla bla ?>) that is save inside a database and have it display on the page

but all getting is the php code as text like
<?php echo bla bla ?>

instead of

bla bla

would this be possible to do ?

thanks

run it thought eval();
http://www.php.net/eval

But do not run eval on untrusted data!

thanks.... what about things like forum template variables (such as {AVATAR_IMG} or something) that if written on a .tpl file look fine but when they are retrieved from a database it shows it as plain text instead of the actuall avatar or whatever. would the eval() thing work for that

[logic_earth]

Those need to be replaced either with regex or str_replace.

sorry i have no idea what that is... any links?

thanks a lot

okay i just quickly read through those on what i found in google and im a little confused on how they could be used to translate template variables

[logic_earth]

well I myself don't have the expertise or the time at this particular moment (busy in the real world) to write up any code for templating. but you will have to look for {AVATAR_IMG} then replace that with the actual data you want.

$s = 'My new image {AVATAR_IMG} on display for the world to see.';
$s = str_replace('{AVATAR_IMG}', 'new data', $s);

soooo... okay i sort of got that.... ima try to work something out, but i can see this being a lot more work than i was hoping for.

but if any other solutions, it would be awesome to hear them.

thanks

There is a better solution. Use an already made templetating engine like Smarty.

Wait - php code coming out as text - you sure PHP is installed? It might not be...

na my problem wasnt really php, it was template variables from my forum, and i thought it could be solved the same way...
