我遇到了相同的问题，并通过下面的链接进行了解决. Symfony声明将报告所有错误，并按设计覆盖您在php.ini中放置的内容(否则它将无法捕获并为您显示漂亮的堆栈跟踪).

I have the same problem and solved it similar to the below link. Symfony declares to report all errors and overrides what you put in php.ini by design (otherwise it couldn't catch & display nice stack traces for you).

因此，您需要通过在AppKernel.php中创建init()函数并设置error_reporting想要的位置来覆盖Symfony2的内置错误报告，可能)进行一些环境检测，以确保您不会在生产中显示错误，例如:

So, you'll need to override Symfony2's built-in error reporting by creating an init() function in your AppKernel.php and setting the error_reporting how you'd like there, along with (probably) some environment detection to make sure you don't display errors in production, for example:

// Add this to app/AppKernel.php
public function init()
{
    if ($this->debug) {
        ini_set('display_errors', 1);
        error_reporting(E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED);
    } else {
        ini_set('display_errors', 0);
    }
}
