Could anybody explain the difference between calling:
zend_eval_string(source, NULL, description)
and
zval retval;
zend_eval_string(source, &retval, description)
It looks to me like if a retval zval is provided there is some sort of
implicit return value pasted onto the script, but it means that a simple
string like: echo "123";
causes a parse error whereas: print "123";
works just fine. That's pretty confusing.
