Cache the response page with buffer support.
Sometimes we just want to simply cache the output response page.

Dependencies
------------

[](#dependencies)

- Symfony Cache >> symfony/cache
- Doctrine Cache >> doctrine/cache

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

[](#installation)

Install this package via [Composer](https://getcomposer.org/).

```
composer require aalfiann/buffer-cache

```

- With SQLite
    Make sure your server already installed `php7-sqlite3`.
- With Redis

    ```
    composer require predis/predis

    ```

Usage
-----

[](#usage)

```
use aalfiann\BufferCache\FilesystemBufferCache;

require 'vendor/autoload.php';

// Callback to modify html source before cache
function modify($buffer) {
    // Test inject javascript
    $javascript = 'console.log("Cache was generated at '.date('Y-m-d H:i:s').'")';
    $buffer = explode('',$buffer);
    $buffer = implode($javascript.'',$buffer);
    return $buffer;
}

$cache = new FilesystemBufferCache([
    // Set ttl cache
    'ttl' => 120
]);

// Start cache
$cache->start();

// Start buffer
//$cache->startBuffer();        // without callback
$cache->startBuffer('modify');  // with callback

// Example to render page
echo '

        Test Page

    Just test to cache the response page
';

// for condition if page failed to render
//$cache->cancelBuffer();

// End cache
//$cache->end();        // without callback
$cache->end('modify');  // with callback

```

Available Constructor
---------------------

[](#available-constructor)

1. Cache with Filesystem

    ```
    use aalfiann\BufferCache\FilesystemBufferCache;
    $cache = new FilesystemBufferCache([
        // options here
    ]);

    ```
2. Cache with SQLite3

    ```
    use aalfiann\BufferCache\SQLiteBufferCache;
    $cache = new SQLiteBufferCache([
        // options here
    ]);

    ```
3. Cache with Redis

    ```
    use aalfiann\BufferCache\PredisBufferCache;
    $cache = new PredisBufferCache([
        // options here
    ]);

    ```

Options in constructor class
----------------------------

[](#options-in-constructor-class)

Here is the default options in constructor class

```
[
    'namespace' => 'page',              // Namespace for cache
    'ttl' => 18000,                     // Time to live cache
    'http_cache' => false,              // Use http cache
    'http_maxage' => 3600,              // Maxage of http cache
    'cache_empty_content' => false,     // Cache empty content
    'cache_query_param' => false,       // Allow cache for url with query parameter
    'ext' => [                          // Allow cache for url with extension
        '.htm','.html','.xhtml','.asp','.aspx','.css',
        '.php','.js','.jsp','.cfm','.md','.xml','.rss'
    ],
    'filesystem' => [                   // filesystem parameters or options
        'path' => 'cache/page'
    ],
    'sqlite3' => [                      // sqlite3 parameters or options
        'table' => 'cache',
        'path' => 'cache/page/page_cache.sqlite3'
    ],
    'predis' => [                       // predis parameters or options.
        'scheme' => 'tcp',
        'host'   => '127.0.0.1',
        'port'   => 6379
    ]
]

```

For more detail information about predis options. See .

Url page with extension
-----------------------

[](#url-page-with-extension)

This will not cache for url page with binary extension like .exe, .rar, .zip, .mp4, .mp3, etc.
You have to whitelist the extension if you want to cache.

The default extensions which is already allowed are:

```
var $ext = [
    '.htm','.html','.xhtml','.asp','.aspx','.css',
    '.php','.js','.jsp','.cfm','.md','.xml','.rss'
];

```

Example if you want to add more `.py` and `.txt`.

```
$cache->addExtension('.py');
$cache->addExtension('.txt');

```

Example if you want just allow `.js` and `.css` only.

1. By options in constructor class

    ```
    $cache = new SQLiteBufferCache([
        'ext' => ['.js', '.css']
    ]);

    ```
2. Or by properties

    ```
    $cache->ext = ['.js', '.css'];

    ```

Http Cache
----------

[](#http-cache)

This library is support http cache but inactivated by default.
If you want to use this, there is three ways :

1. By options in constructor class

    ```
    $cache = new SQLiteBufferCache([
        'http_cache' => true,
        'http_maxage' => 3600
    ]);

    ```
2. Or by function

    ```
    $cache->useHttpCache(3600);

    ```
3. Or by properties

    ```
    $cache->http_cache = true;
    $cache->http_maxage = 3600;

    ```

Note
----

[](#note)

- I only create buffer cache with using **Filesystem**, **SQLite3** and **Redis**, so contribution are welcome.
