Trouble using eval()

[thincom2000]

Okay I got around escaping the colons. But here's what I'm trying to do:

The user enters a string containing a list of variables in an input field. These variables then need to be interpreted as globals, but the following oh so simple code won't work:

PHP Code:

global eval('return $user_entered_globals;'); 


EDIT: Never mind. Although this would be nice to know for the future, I decided against user-entered globals this time around.
