Question

我有一个包含用户的表，每个用户都有一个城市。我使用enter image description here来显示每个城市的用户数量

这是我的代码

$em = $this->getDoctrine()->getManager();
        $classes = $em->getRepository('MyBundle:User')->findAll();

        $data= array();
        $stat=array();
        foreach($classes as $class) {

            $query = $em->createQuery("SELECT COUNT(u) FROM MyBundle:User u WHERE u.city = ?1");
            $query->setParameter(1, $class->getCity());


            if (!in_array($class->getCity(), $stat)) {
                array_push($stat,$class->getCity(),($query->getSingleScalarResult() *1)/1);
            }


        }
    array_push($data,$stat);

我只获得了第一个城市的用户数量，所以看起来我的foreach循环效果不佳..任何帮助都将不胜感激！

这是我的工作代码，以防有人需要它：

$em = $this->getDoctrine()->getManager();
$classes = $em->getRepository('MyBundle:User')->findAll();

$data= array();
$stat=array();
$hm=array();

$query = $em->createQuery("SELECT COUNT(u) FROM MyBundle:User u WHERE u.city = ?1");

foreach($classes as $class) {

    $query->setParameter(1, $class->getCity());

        if (!in_array($class->getCity(), $hm)) {

            unset($stat);
            $stat = array();
            array_push($stat, $class->getCity(), (int)$query->getSingleScalarResult());
            array_push($hm, $class->getCity());
            array_push($data,$stat);

        }

}

PieChart只显示一个元素
