PHP - 从数据库获取值并显示已知值

Question

I've been searching for this for a while now.. It's probably very simple but I just can't seem to get it right.

My website uses a file with translations. Every translation has it's own variable.
Like: $_text_login (which translates to: Login or Aanmelden or Derp).

I've made a menu table within my database. One of the menu items has the text: $_text_login

Obviously, when I get the menu information, it doesn't show the currently set value of the variable, it just shows $_text_login.

I've tried eval() but that doesn't work..

Can anyone help?

I would not recommend this approach and I would santize the variable name, but from the sounds of it, you could achieve what you are saying with:

echo eval('return '. $item  . ';');

Where $item would be the result from the database.
