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.
Note: This function was added in PHP 4.
