Navcat bank connection

I would like to resolve a data connection problem in navcat. I can not send the data to the database and I do not know what I'm doing wrong, if anyone can give me some suggestions, the connection is mysql .

config.php:

<?php 
$config = array(
    'title'  => 'Via Toscana',
    'test'   => 1, /* 1 em testes 0 em produção. */
    'errors' => 1,
    'rewrite' => 0
    );

if($config['test'] == 1) {
    $config['db_host'] = 'dev';
    $config['db_base'] = 'via';
    $config['db_user'] = 'via';
    $config['db_pass'] = 'abc123';
}else{
    $config['db_host'] = 'dev';
    $config['db_base'] = 'via';
    $config['db_user'] = 'via';
    $config['db_pass'] = 'abc123';
}

class objConexao {
    private $objConn;
    public function __construct() {
        global $config;
        $this->objConn = mysql_connect($config['db_host'], $config['db_user'], $config['db_pass']) or trigger_error(mysql_error(), E_USER_ERROR);
        $link = mysql_select_db($config['db_base'], $this->objConn);

    }
    public function __destruct() {
        @mysql_free_result();
        @mysql_close();
    }
    public function fcnConn(){
        return $this->objConn;
    }
}

$objConn = new objConexao();
$conn = $objConn->fcnConn();
?>

                                </div>
       <ul class="row">

    </div>
    </form>

envia.php:

<?php
$nome = $_POST['cliente_nome'];
$telefone = $_POST['cliente_telefone'];

$sql .= "('$nome', '$telefone', '$email','$bairro','$rua','$complemento')";
echo $sql;exit();
mysql_query($sql,$objConn) or die(mysql_error());
mysql_close($objConn);
