Caching of an unchanging array is typically prepared on one computer and used on another.

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

[](#installation)

```
composer require ap-lib/persistent-cache
```

Features
--------

[](#features)

- Interface for saving and loading arrays
- Implementation for saving and loading arrays to a PHP file

Requirements
------------

[](#requirements)

- PHP 8.3 or higher

Getting Started
---------------

[](#getting-started)

```
$original_array = [
    "hello" => "world",
    "foo"   => "boo",
];

// Set up the cache object (in this case, it's just a filename)
$cache = new PhpFilePersistentCache("data.php");

// Store the array in the cache
$cache->set($original_array);

// Retrieve the array from the cache
$retrieved_array = $cache->get();

// RESULT: $retrieved_array will equal $original_array
```

**IMPORTANT**: The array can only contain primitive data types such as int, float, bool, string, and null:

```
$original_array = [
    "hello" => "world",
    "foo"   => "boo",
    "object" => new Exception("hello world"),
];

$expected_array = [
    "hello" => "world",
    "foo"   => "boo",
    "object" => null,
];

// Set up the cache object (in this case, it's just a filename)
$cache = new PhpFilePersistentCache("data.php");

// Store the array in the cache
$cache->set($original_array);

// Retrieve the array from the cache
$retrieved_array = $cache->get();

// RESULT: $retrieved_array will equal $expected_array
```
