示例

示例 #1 Ds\Sequence::get() example

<?php
$sequence = new \Ds\Vector(["a", "b", "c"]);

var_dump($sequence->get(0));
var_dump($sequence->get(1));
var_dump($sequence->get(2));
?>

以上示例的输出类似于：

string(1) "a"
string(1) "b"
string(1) "c"

示例 #2 Ds\Sequence::get() example using array syntax

$sequence = new \Ds\Vector(["a", "b", "c"]);

var_dump($sequence[0]);
var_dump($sequence[1]);
var_dump($sequence[2]);
?>

以上示例的输出类似于：

string(1) "a"
string(1) "b"
string(1) "c"
