Variables in array.

Additional provides module for Laminas for configurations.

Usage

Sometimes you want to use same values in other places in your config. What are you doing?

<?php $myIp = '127.0.0.1'; return [ 'db' => $myIp, 'memcache' => $myIp, ];

Of course it's working, but when you want to share $myIp between separate config files thats challange! ZfSnapVarConfig make a magic here!

$data = [ 'ips' => [ 'local' => '127.0.0.1', 'memcache' => '127.0.0.2', 'smtp' => '127.0.0.3' ], 'email' => new ZfSnapVarConfig\Value\Env('ADMIN_EMAIL'), 'db' => ZfSnapVarConfig\Value\Path::fromString('ips/local'), 'memcache' => ZfSnapVarConfig\Value\Path::fromString('ips|memcache', '|'), 'email' => [ 'smtp' => ZfSnapVarConfig\Value\Path::fromArray(['ips', 'smtp']), 'default-mail' => ZfSnapVarConfig\Value\Path::fromString('email'), 'reply-to' => ZfSnapVarConfig\Value\Path::fromString('email'), 'other-address' => new ZfSnapVarConfig\Value\Path('ips', 'smtp'), ], ]; $service = new ZfSnapVarConfig\VarConfigService(); $replaced = $service->replace($data); // or $service($data); assertSame([ 'ips' => [ 'local' => '127.0.0.1', 'memcache' => '127.0.0.2', 'smtp' => '127.0.0.3' ], 'email' => 'your@email.com', 'db' => '127.0.0.1', 'memcache' => '127.0.0.2', 'email' => [ 'smtp' => '127.0.0.3', 'default-mail' => 'your@email.com', 'reply-to' => 'your@email.com', 'other-address' => '127.0.0.3', ], ], $replaced);

On this moment you can use selectors:

• ZfSnapVarConfig\Value\Path
• ZfSnapVarConfig\Value\Env
• ZfSnapVarConfig\Value\Callback

You can write your own value manipulator. Just implement ZfSnapVarConfig\Value and create instance in your config.

How to install?

Via composer.json

composer require snapshotpl/zf-snap-var-config

If you want to use this library as Laminas module add ZfSnapVarConfig to your application.config.php file.
