我有一个 ZF2 应用程序从 Web 服务器正常运行。我需要从命令行运行一些操作，因为我想要执行一些计划任务（cron 作业）。
所以我找到了这些有用的链接：Zend框架的官方文档 http://framework.zend.com/manual/2.1/en/modules/zend.console.introduction.html, 萨姆索纳西克的博客 http://samsonasik.wordpress.com/2012/09/05/zend-framework-2-step-by-step-create-console-application/。
我首先在GeneratePdf 模块中的module.config.php 上添加控制台路由。这是控制台路由的一段。
'console' => array(
'router' => array(
'routes' => array(
'generate' => array(
'options' => array(
'route' => 'generate all [--verbose|-v]',
'defaults' => array(
'__NAMESPACE__' => 'GeneratePdf\Controller',
'controller' => 'GeneratePdf',
'action' => 'generateAll'
),
),
),
)
)
),
我在GeneratePdf控制器类上有一个动作，这里是这个动作的段代码：
public function generateAllAction() {
die('Is it working?');
set_time_limit(150000);
// reading directory
$d = dir('public/pdf/');
$files = array();
while (($file = $d->read()) !== false) {
$files [] = $file;
}
$d->close();
我没有包含上述操作的所有代码，因为它有很多行。它可以在网络浏览器中正常工作。
为了从控制台运行，我在 ubuntu 13.10 的终端中输入了以下命令：
php public/index.php generate all -v
我的终端上有一堆错误堆栈跟踪：
PHP Notice: Undefined index: APPLICATION_ENV in /var/www/zf2-reporting/publi/index.php on line 11

它在index.php文件中的$_SERVER超级全局变量“APPLICATION_ENV”中抛出未定义的索引。我已在可用站点的虚拟主机文件中定义了应用程序环境。它可以在浏览器中正常工作。如果我切换应用程序环境它就可以工作。另一个问题是 PHP 警告：date()。
我在 php.ini 中正确定义了日期。这里是：
date.timezone = Asia/Kathmandu
虽然这不是大问题，但我可以通过在 index.php 上使用此函数来传递日期：
date_default_timezone_set("Asia/Kathmandu");
我还尝试通过以下代码直接在index.php中设置APPLICATION_ENV：
if(!isset($_SERVER['APPLICATION_ENV'])){
$_SERVER['APPLICATION_ENV'] = 'development';
}
当我再次触发此命令时： php public/index.php generated all -v
我在终端没有输出。它没有打印以下文本：“它有效吗？”它位于我的动作文件第一行的 die 函数中。
我对输出完全感到困惑。没有什么可调试的。我的意思是它没有抛出任何错误，那么我该如何调试它。
我完全不知道如何从命令行传递 APPLICATION_ENV 或者可能还有其他选项来设置它。我也尝试在 bashrc 文件中设置路径，但它也不起作用。
我想我已经涵盖了这个问题中所有必需的代码部分/错误。如果有什么遗漏，请告诉我。 :)
谢谢。
