示例 #1 Ds\Vector::insert() example

<?php
$vector = new \Ds\Vector();

$vector->insert(0, "e");             // [e]
$vector->insert(1, "f");             // [e, f]
$vector->insert(2, "g");             // [e, f, g]
$vector->insert(0, "a", "b");        // [a, b, e, f, g]
$vector->insert(2, ...["c", "d"]);   // [a, b, c, d, e, f, g]

var_dump($vector);
?>

以上示例的输出类似于：

object(Ds\Vector)#1 (7) {
  [0]=>
  string(1) "a"
  [1]=>
  string(1) "b"
  [2]=>
  string(1) "c"
  [3]=>
  string(1) "d"
  [4]=>
