Returns an array in which each element is the
corresponding member of the current user-defined function's
argument list. func_get_args() will
generate a warning if called from outside of a function
definition.
?php function foo() { $numargs = func_num_args(); echo "Number of arguments: $numargs br \n"; if ($numargs = 2) { echo "Second argument is: " . func_get_arg (1) . " br \n"; } $arg_list = func_get_args(); for ($i = 0; $i $numargs; $i++) { echo "Argument $i is: " . $arg_list[$i] . " br \n"; } } foo (1, 2, 3); ? |
func_get_args() may be used in
conjunction with func_num_args() and
func_get_arg() to allow user-defined functions to
accept variable-length argument lists.
注: This function was added in PHP 4.
