php tags from a database.

[Tidus]

Hello!

I currently have <?php ?> tags in my database but when i look at the page that calls that record nothing shows up, it just shows the tags in the page source.

Does anyone know how to fix this?

Broken as designed?

In other words, is there a specific reason you store PHP source code in the database? Why don't use a simple include_once or require_once to import PHP source code into a script? Perhaps a little bit of source code helps clearing up your issue...

.. you can eval($from_db) as well though in that case you dont need the <? ?> tags as eval() appears to add them for you, but I am with Mordred in that it seems a strange way to go about things !

Hey

If you are retrieving from a DB, then how are you going to make PHP process the script?

Using eval() just like firepages said.

Hey

firepages says eval() adds the tags and doesn't mention script execution. But sorry, I didn't know it also executes the script, I have never called script from a DB.

Ok so the row is called news.

sorry. i am there and cant figure it out?

eg


<?
$yaks=mysql_query("SELECT code FROM tester");
$str=mysql_result($yaks,0);
eval($str);
?>



where code in tester is..


for($x=0;$x<=10;$x++){echo "allo from MySQL \n<br />";}


note that eval() can be a real pain at times.
