battis / appmetadata example snippets


// instantiate a new mysqli database connection
$sql = new mysqli('localhost', 'root', 's00pers3kr3t', 'demo-db');

// first use (create database tables -- only needs to happen once!)
Battis\AppMetadata::prepareDatabase($sql);

// instantiate our metadata array
$metadata = new Battis\AppMetadata($sql, 'my-unique-app-key');

// store something into the database
$metadata['X'] = 'foobar';

// read something out of the database
echo $metadata['X']; // 'foobar'

// use one metadata value to derive another
$metadata['Y'] = '@X again'
echo $metadata['Y']; // 'foobar again';

// derived values update automagically
$metadata['X'] = 'xoxo';
echo $metadata['Y']; // 'xoxo again';

// remove something from the database
unset($metadata['X']);
echo $metadata['Y']; // '@X again', since no value X to derive from
