##Usage:

Create a child class like this (A sample child class has been provided as sampleDbUpdateService.php): class DbUpdateService extends \Scriptburn\UpdateDb {

// will be called for target db version 1
public function update_routine_1()
{
    /* make sure to return true
    other wise db update will stop propogating
    and update process will run again
     */
    return true;
}
// will be called for target db version 2
public function update_routine_2()
{
    /* make sure to return true
    other wise db update will stop propogating
    and update process will run again
     */
    return true;
}

}

Next we will Call the actual function that checks if db update is needed. Best place for this code will be in a middleware // make sure composer.json has a key named dbversion in it $optionalVersionData=['type' => 'composer', 'path' => "/path/to/composer.json"];

$dbUpdateCheck = new App\Services\DbUpdateService(< instance of \ScriptBurn\Settings >, < instance of pdo connection >, $optionalVersionData);

//If you passed $optionalVersionData as 3rd parameter to App\Services\DbUpdateService constructor you do not need to pass current db version to method maybeUpdate as second parameter $dbUpdateCheck->maybeUpdate('scriptburn/git-auto-deploy',< optional current db version no >');
