PHP tag in database

[Subhash]

Hello,
I have a database that consists of text. This text contains php code
that needs to be processed before echoing it on the browser. A
pseudocode may be:

<?php
/* connect to database */

/* for each record
process the php text in database */
?>

Simply echoing the text will not make the php tags to be processed.
Please let me know if you have any ideas or opinions on how to make
the text information in database to be processed.

Thanks!

Look up eval (but be VERY careful what you execute, don't let anyone
else write it to your database)

Thanks Kevin. Thats really helped. But what if the text was something
like this:

<htmlcode>Bla h Blah</htmlcode>
<?php echo "xyz"; ?>
<htmlcode>Bla h Blah</htmlcode>

When you do an eval on this it does not work, which is correct. Is
there anyway to properly handle the above case?

I'd try:

<?php
$text = '<htmlcode>Bla h Blah</htmlcode>
<?php echo "xyz"; ?>
<htmlcode>Bla h Blah</htmlcode>';

eval('?>' . $text);
?>

How about ... write your data to a temp file and then include that file.

Look at the user notes <http://in2.php.net/eval> especially
eval_html()

Pedro,
Your suggestion worked great! But I don't understand how? I mean how
does adding '?>' to the $text make it work?

Thanks

The '?>' simply says to php:

- Hey! Quit "PHP mode" and evaluate what follows as HTML, parsing
whatever you find between <?php and ?> as PHP.
