Question

我有一个简单的代码，当我print_r时，这个是输出：

Array

    [0] => App\Entities\EibPerson Object

我的代码：

$person = $this->em->getRepository('App\Entities\EibPerson')->findAll();
print_r($person);

我真正想要的只是得到这个：

我怎么可能这样做？因为我想json_encode数组但我得到一个空的json ..

Answer 1

使用最大深度进行调试

您可以使用Doctrine Dump的maxDepth变量。您可以使用\Doctrine\Common\Util\Debug::dump($variable, $depth);显示没有代理信息的doctrine输出。

更易读的输出

如果您使用的是symfony 2.6或更高版本，我强烈建议您使用dump()代替var_dump()或print_r()。转储显示格式良好的彩色输出，您可以展开/隐藏行。

最后......到json

要将对象导出到json，我建议你使用序列化器和规范化器服务，你可以找到here in the documentation

教义打印对象中的所有内容
