func_get_arg -- Return an item from the argument list
Syntax
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.
This function cannot be used directly as a function parameter. Instead,
its result may be assigned to a variable, which can then be passed to
the function.
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.
