I need to simulate a call to eval() and the only function
that seems to be able to do it is zend_eval_string().
Although it evaluates the string when I put NULL as second
parameter (retval_ptr), it doesn't work (parse error) when I
want to simulate the new behavior of PHP4 eval() (ie. with a
return value)

Is it possible to change the existing zend_eval_string (I
think not cause pcre and assert use it this way already) ?

If not, is it possible to have a new function that would
behave like eval(), with the same parameters as
zend_eval_string (I want to be able to specify a name on the
string) ?

Thanx

Hi,

I commented out a few lines from zend_eval_string() and now
it behaves the right way.

Here are the line numbers I removed (corresponding to the
function zend_eval_string):
zend_execute_API.c: 492 to 498, 501.

Note that I'm not especially asking to modify this function,
but to add a new function that would behave like the real
eval() statement.

And it would be good if I this new function is available
before 4.0.5 is out, cause the midgard module relies on it.

Thanks

I've found a workaround, it's to replicate the function
zend_eval_string() in my own module, less the few lines that
pose problem.

I consider this as a workaround only, since I'm not sure if
the code used in that function follows the exact Zend API,
so I will let this feature request open.

It seems current master does not have this issue.
Please reopen if there is.
