Right now you need to test in version 5.3 of PHP. I'll try fix it in the
next release.
PHP Notes:
Because this function depends on the current scope to determine
parameter details, it cannot be used as a function parameter in
versions prior to 5.3.0. If this value must be passed, the
results should be assigned to a variable, and that variable
should be passed.
