xdebug 忽略错误抑制 - 未安装尖叫
xdebug ignoring error suppression - scream not installed
我已经安装了 xdebug，并且正在 Ubuntu 14.10 笔记本电脑上使用 Sublimetext 3 进行开发。我的问题是使用 xdebug 解析的 @ 符号抑制了错误。因此，在我整洁的 mvc 架构中的任何自动加载器都意味着我必须反复按 run 快捷键，以最终查看我的更改是否有效。非常烦人。更重要的是我没有启用 scream 。在我的 phpinfo() 中搜索 scream 只会产生 xdebug.scream = Off.
所以...在我的自动加载器中，以下内容将触发 xdebug 警告。
@include $class . ".php";
我是否必须特别告诉 xdebug 不要忽略错误？有没有办法让我以编程方式声明我希望 xdebug 忽略 @include( 警告但触发 include( 警告？
感谢任何帮助。

如果您的 IDE 甚至因被抑制的错误而中断，那么我怀疑这是一个选择。但是，我的建议是让它不要因任何错误而中断，因为您可以很容易地在错误日志中看到带有尾巴的错误，而且我认为被抑制的错误不会出现在那里。但是，这对您来说是个问题，这听起来像是您在对很多错误使用错误抑制……只是我的两分钱，但情况永远不应该如此。
http://www.sitepoint.com/why-suppressing-notices-is-wrong/
即使抑制错误也会降低应用程序的性能...因此，如果您使用抑制来避免测试未定义的索引等，例如
$var = @$_POST['name']
只是为了避免这样做：
$var = isset($_POST['name']) ? $_POST['name'] : null;
那么，你应该重新考虑你的所作所为，停止使用压制。例如，最好写一个包装器 class:
class Input {
private $_input;
public function __construct( array $data ) {
$this->_input= $data;
}
public function get( $name ) {
return isset($this->_input[$name]) ? $this->_input[$name] : null;
}
}
这样做不仅可以让您不必抑制错误，而且可以使您的代码更加灵活——尤其值得一提的是——如果注入了输入，则能够通过单元测试 运行。
$data = new Input($_POST);
$var = $data->get('name');
