(PHP 4 >= 4.0.0)
func_get_arg -- Return an item from the argument list
Description
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.
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.
