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);

The above example will output:

object(pht\Vector)#1 (1) {
  [0]=>
  int(0)
}
object(pht\Vector)#1 (2) {
  [0]=>
  int(0)
  [1]=>
  int(1)
}
object(pht\Vector)#1 (1) {
  [0]=>
  int(0)
}
