Yii 2 PHP file cache

Yii 2 cache component that uses native PHP files to store cache data so:

• it's possible to improve a PHP performance by storing a precompiled data bytecode in a shared memory (objects will be serialized though)
• allows to include an arbitrary PHP code to bootstrap something
• it's fully compatible with the standard Yii 2 cache interface

Installation

The preferred way to install this extension is through composer.

Either run

composer require "sergeymakinen/yii2-php-file-cache:^2.0"

or add

"sergeymakinen/yii2-php-file-cache": "^2.0"

to the require section of your composer.json file.

Usage

Set the following Yii 2 configuration parameters:

[
    'components' => [
        'phpCache' => [
            'class' => 'sergeymakinen\yii\phpfilecache\Cache',
        ],
    ],
]

And you can use it like any Yii 2 cache class:

Yii::$app->phpCache->set('foo', 'bar')

Caching values with a PHP code

If you need to execute any PHP bootstrap code before you get a value from a cache, pass a sergeymakinen\yii\phpfilecache\ValueWithBootstrap instance with the value and a PHP code (which can be multiline of course) as a string to set():

use sergeymakinen\yii\phpfilecache\ValueWithBootstrap;

Yii::$app->phpCache->set(
    'foo',
    new ValueWithBootstrap(
        'bar',
        'Yii::$app->params[\'fromCache\'] = true;'
    )
);

Since version 1.1 you can also pass a Closure instead of a PHP code:

use sergeymakinen\yii\phpfilecache\ValueWithBootstrap;
use yii\helpers\StringHelper;

Yii::$app->phpCache->set(
    'foo',
    new ValueWithBootstrap('bar', function () {
        \Yii::$app->params['fromCache'] = true;
        \Yii::$app->params['name'] = StringHelper::basename('/etc/config');
    })
)
