<simpara>
Returns an array in which each element is a copy of the corresponding
member of the current user-defined function's argument
list. <function>func_get_args</function> will generate a warning
if called from outside of a function definition.
This function cannot be used directly as a function parameter. Instead,
its result may be assigned to a variable, which can then be passed to
the function.
</simpara>
<note>
<simpara>
This function returns a copy of the passed arguments only, and does not
account for default (non-passed) arguments.
