From
http://www.php.net/manual/en/function.eval.php :
"A return statement will terminate the evaluation of the string
immediatley. In PHP 4 you may use return to return a value that will
become the result of the eval() function while in PHP 3 eval() was of
type void and did never return anything."
So, if you're using PHP4, just ensure that there is a return
in$php_code that returns the desired value:
$thing = eval($php_code);
It's helpful to read the notes at the above URL - escaping things
correctly for eval() can be tricky...
