Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

In your example there is no function in your eval\'d code.

I see.  I thought the eval() was run in the current 
context, but in fact it runs in its own completely 
separate PHP context?  But that doesn't make sense since 
you can make variable assignments etc within the eval().  
It seems if one can make use of pre-existing variables 
within the eval, it should also know it's inside a 
function.
