Description
mixed
func_get_arg ( int arg_num)
Returns the argument which is at the
arg_num'th offset into a user-defined
function's argument list. Function arguments are counted starting
from zero. func_get_arg() will generate a
warning if called from outside of a function definition.
If arg_num is greater than the number of
arguments actually passed, a warning will be generated and
func_get_arg() will return FALSE.
func_get_arg() may be used in conjunction with
func_num_args() and
func_get_args() to allow user-defined
functions to accept variable-length argument lists.
