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... - steve >- Original Message - >From: Thomas Weber <> >To: Php-General <> >Sent: Wednesday, January 24, 2001 10:14 AM >Subject: AW: [PHP] eval() to string??? > > >> try >> >> eval("\$php_code;"); >> >> -Ursprüngliche Nachricht- >> Von: [ rswfire ] [mailto:[EMAIL PROTECTED]] >> Gesendet: Mittwoch, 24.
