Question

我有这个文件夹结构

[-] myapp/
    [+] app/
    [-] lib/
        [-] vendor/
            [-] doctrine/
                [-] Doctrine/
                        Common/
                        DBAL/
                        Symfony/
                [+] bin/
    [-] sites/
        [-] default/
            [-] test/
                    test-doctrine-dbal.php

我尝试了文档中的代码

    <?php

use Doctrine\Common\ClassLoader;

require dirname(__FILE__).'/../../../lib/vendor/doctrine/Doctrine/Common/ClassLoader.php';

$classLoader = new ClassLoader('Doctrine', dirname(__FILE__).'/../../../lib/vendor/doctrine/Doctrine/DBAL/DriverManager.php');
$classLoader->register();

$config = new \Doctrine\DBAL\Configuration();
$connectionParams = array(
    'dbname' => 'cdcol',
    'user' => 'root',
    'password' => '',
    'host' => 'localhost',
    'driver' => 'pdo_mysql',
);
$conn = DriverManager::getConnection($connectionParams, $config);

$sql = "SELECT * FROM cds";
$stmt = $conn->query($sql);
while ($row = $stmt->fetch()) {
    echo $row['titel'];
}
?>

我收到警告：

Warning: require(D:\xampp\htdocs\myphp\sites\default\test/../../../lib/vendor/doctrine/Doctrine/DBAL/DriverManager.php\Doctrine\DBAL\Configuration.php) [function.require]: failed to open stream: No such file or directory in D:\xampp\htdocs\myphp\lib\vendor\doctrine\Doctrine\Common\ClassLoader.php on line 148

错误：

Fatal error: require() [function.require]: Failed opening required 'D:\xampp\htdocs\myphp\sites\default\test/../../../lib/vendor/doctrine/Doctrine/DBAL/DriverManager.php\Doctrine\DBAL\Configuration.php' (include_path='.;D:\xampp\php\PEAR') in D:\xampp\htdocs\myphp\lib\vendor\doctrine\Doctrine\Common\ClassLoader.php on line 148

我对PHP命名空间了解不多。在PHP手册中阅读PHP命名空间仍然无法解决问题。如果我想将Doctrine DBAL与该目录结构一起使用，该代码是否正确？

Answer 1

您需要将Doctrine库路径添加到include_path。请参阅get_include_path和set_include_path PHP函数。

Answer 2

这对我来说是错误的（来自警告）

D:\xampp\htdocs\myphp\sites\default\test/../../../lib/vendor/doctrine/Doctrine/DBAL/DriverManager.php\Doctrine\DBAL\Configuration.php

我对PHP知之甚少，但我不认为文件路径可以解决。现在，请尝试删除 dirname（ _ __ FILE_ _ _），然后只修改其中的路径。

Answer 3

ClassLoader构造函数的第二个参数无效：

$ classLoader = new ClassLoader（'Doctrine'， dirname（_ FILE _）。'/ .. / .. / .. / lib / vendor / doctrine / Doctrine / DBAL /DriverManager.php'）;

第二个参数应该是Doctrine目录的include path，不应该是文件。

因此，正确的行是：

$ classLoader = new ClassLoader（'Doctrine'，'/../../../ lib / vendor / doctrine /'）;

如何使用Doctrine DBAL？
