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.
Note: This function was added in PHP 4.
