Example #1 Resizing a vector
<?php
use pht\Vector;
$vector = new Vector(1);
var_dump($vector);
$vector->resize(2, 1);
var_dump($vector);
$vector->resize(1, 2); // unused second arg
var_dump($vector);
以上例程会输出：
object(pht\Vector)#1 (1) {
[0]=>
int(0)
}
object(pht\Vector)#1 (2) {
[0]=>
int(0)
[1]=>
int(1)
}
object(pht\Vector)#1 (1) {
