pht\Vector::insertAt — Inserts a value into the vector

### Description

public pht\Vector::insertAt ( mixed `$value` , int `$offset` ) : void

This method inserts a value at the specified offset into the vector (in linear time). The vector will automatically be resized if it is not large enough.

### Liste de paramètres

`value`

  The value to be inserted into the vector. This value will be serialised (since it may be passed around between threads).

`offset`

  The offset at which the value will be inserted at. This offset must be within the 0..N range (inclusive), where N is the size of the vector. Inserting at position N is the equivalent of using pht\Vector::push(), and inserting at position 0 is the equivalent of using pht\Vector::unshift(). Attempting to insert at offsets outside of this range will result in an Error exception.

### Valeurs de retour

No return value.

### Exemples

Exemple #1 Inserting a value into a vector

`<?php
use pht\Vector;
$vector = new Vector();
$vector->insertAt(3, 0); // insert 3 at start
$vector->insertAt(1, 0); // insert 1 at start (before 3)
$vector->insertAt(2, 1); // insert 2 in middle (after 1 and before 3)
var_dump($vector);`
