func_get_arg
(PHP 4)
Description
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.
?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";}} foo (1, 2, 3);?
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.
蛁: This function was added in PHP 4.
