eval in php-module

Hi! For a current project I am working on a custom module for php4. Unfortunately, I am having a problem trying to evalute php code in this module. I need a function that basically replicates the eval() statement from php with some minor changes. I tried 'zend_eval_string("$test = 123;", &retval ELS_DC);', wich workds, but only for simple statements. Others, such as "$test = 123; $test2= 345;" do not work, nor does the echo construct. Is zend_eval_string the right function for this purpose and what is the exact syntax? Where can I find the implementation of eval() in the php source? What would be the best way to implement such a function? Please cc: to kr@someon.com since I am currently not subscribed to the list. Regards, --kr
