(PHP4 >= 4.0b4)

Func_get_args---&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Returns an array of argument lists containing functions

Syntax: int Func_get_args (void)

Description:

Returns an array of elements that correspond to the number of parameter columns for the current user-defined function. If you call this function from outside the function definition, func_get_arg () will produce a warning.

Example:

<?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 () can be used to combine Func_num_args () and Func_get_arg () to allow a user-defined function to accept a variable-length parameter list.

Note: This function is a new function in PHP4
