not work in Phlacon 3.0 and PHP 7

[engsere]

I know that this lib is not support phalcon 3 and php7, but few small changes make it run.
I had to install php7.0-sybase and php-sybase

All changes are in Phalcon/Db/Adapter/Pdo/Sqlsrv.php

first: change declaration of connect function:

from: public function connect($descriptor = null)
to: public function connect(array $descriptor = null)

second: change connection via PDO
from:
$this->_pdo = new \PDO("sqlsrv:server={$descriptor['host']}:1433;database={$descriptor['dbname']}", $descriptor['username'], $descriptor['password'], $options);
to:
`$options[\PDO::ATTR_ERRMODE] = \PDO::ERRMODE_EXCEPTION;
$options[\PDO::ATTR_STRINGIFY_FETCHES] = true;

    $dsn= "dblib:host=".$descriptor['host'].":1433;dbname=".$descriptor['dbname'].";";
    $dbusername=$descriptor['username'];
    $dbpassword=$descriptor['password'];

    $this->_pdo = new \PDO($dsn,$dbusername,$dbpassword);
    $this->_pdo->setAttribute(\PDO::ATTR_ERRMODE,\PDO::ERRMODE_EXCEPTION);`

third and last: change declaration $dialectClass variable from:

$dialectClass = 'Phalcon\\Db\\Dialect\\' . $this->_dialectType;
to: $dialectClass = 'Phalcon\\Db\\Dialect\\' . ucfirst($this->_dialectType);

that changes help me and let use this lib co connect with mssql.
