A small PHP package to help you perform a search in large scale arrays with a dramatically improved performance.

Installation
------------

[](#installation)

You can install the package via composer:

```
composer require ezzaze/binary-search
```

Usage
-----

[](#usage)

```
use Ezzaze\BinarySearch\BinarySearch;

$haystack = range(1,1000000);
$result1 = BinarySearch::exists(500, $haystack); //true
$result2 = BinarySearch::exists(0, $haystack); //false
```

If you have an already pre-sorted array you can skip the sorting before search by supplying false to the 3rd parameter

```
use Ezzaze\BinarySearch\BinarySearch;

$haystack = range(1,1000000);
$result = BinarySearch::exists(500, $haystack, false);
```

The package can also be used to search for multi-demensional array within another array as shown below

```
use Ezzaze\BinarySearch\BinarySearch;

$haystack = array_chunk(range(1,1000000), 2);
$result1 = BinarySearch::exists([500,501], $haystack); //true
$result2 = BinarySearch::exists([501, 502], $haystack); //false
```
