我需要帮助才能正确使用＆＃34;其中＆＃34;在我的查询到articleController 或者如果你有更好的解决方案

<?xml version="1.0" encoding="UTF-8"?>
<project name="Test" default="build">
    <!-- ============================================  -->
    <!-- Target: start                                 -->
    <!-- ============================================  -->
    <target name="start">
        <echo msg="Start build" />
    </target>
    <!-- ============================================  -->
    <!-- Target: prepareDirectory                      -->
    <!-- ============================================  -->
    <target name="prepareDirectory" depends="start">
        <echo msg="Making directory build ./build" />
        <mkdir dir="./build" />
        <echo msg="Making directory install ./install" />
        <mkdir dir="./install" />       
    </target>       
    <!-- ============================================  -->
    <!-- Target: build                                 -->
    <!-- ============================================  -->
    <target name="build" depends="prepareDirectory">
        <echo msg="Copying files to build directory..." />

        <echo msg="Copying ./about.php to ./build directory..." />
        <copy file="./about.php" tofile="./build/about.php" />

        <echo msg="Copying ./browsers.php to ./build directory..." />
        <copy file="./browsers.php" tofile="./build/browsers.php" />

        <echo msg="Copying ./contact.php to ./build directory..." />
        <copy file="./contact.php" tofile="./build/contact.php" />

一种可能的解决方案

public function articleAction() {
    $repository = $this->getDoctrine()->getRepository('appBundle:Article');
    $article = $repository->createQueryBuilder('a')
            ->select('a.id','a.title','a.num')
            ->orderBy('a.num', 'DESC')
            ->getQuery()
            ->getOneOrNullResult();

    return $this->render('appBundle:articles:article.html.twig', array(
                'article'=>$article)
            );
}
