Database file echoing problem.

[iStriide]

I have a file in a mysql database and when I echo it shows all of the php code from the file in the database on the page when it is echoed. How can I fix this problem. I notice a lot of websites coded from php have things like ?go=register or ?page=login something like that. Could you guys tell me how to do things like that. Im pretty sure when people do things like ?go=register the register is the code of a file in a mysql database.

Those are URL parameters you can retrieve with GET.

 

file.php \\ No url parameters

file.php?do=whatever \\ One url parameter

file.php?do=whatever&action=whatever&etc=etcetera \\ Multiple url parameters

 

Then you can retrieve these via $_GET super variable.

 

For instance: echo $_GET['do'] \\ Prints out 'whatever'

 

 

Never trust user submitted data, including url parameters. Always sanitize this data.

php code is not usually locate in database. It locates in files and uses by include_once(or similar) command.

If your code is a string from database you must use eval command to run it.
