PHP Ds\Vector Functions Complete Reference

A Vector Data Structure is used to store the sequence of values in a contiguous memory buffer which grows and shrinks automatically. The vector data structure mapped the index value to its index buffer and the growth factor isn't bound to a specific multiple or exponent. It is the efficient Data Structure in PHP 7 to provide the alternative of an array. 

Requirements: PHP 7 is required for both extension and the compatibility polyfill.

Installation: The easiest way to install data structure by using PECL extension.

pecl install ds

Syntax:

public Ds\Vector:: Function

Example: Below programs illustrate the Ds\Vector::find() Function in PHP:

<?php

// Declare a Vector elements
$vector = new \Ds\Vector([1, 2, 3, 4, 5]);

// Display the vector elements
var_dump($vector);

// Use find() function to find
// the index value of element
var_dump($vector->find(1));

var_dump($vector->find(5));

var_dump($vector->find(8));

var_dump($vector->find("Geeks"));

?>

Output:

object(Ds\Vector)#1 (5) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  int(3)
  [3]=>
  int(4)
  [4]=>
  int(5)
}
int(0)
int(4)
bool(false)
bool(false)
