Question

我在调试PHP应用程序时遇到困难。

当我包含我的php文件时，不会引发任何异常。我尝试使用不会触发的set_error_handler，但error_get_last（）返回null。

set_error_handler(function() {
   echo 'Here is your error!';
   var_dump(error_get_last());
   echo 'Sike!';
});
try {
    include('viewer.php');
} catch (Exception $e) {
    echo 'I really ought to tell you something went wrong here. But I won\'t';
}
restore_error_handler();
exit();

输出：

Here is your error!NULL Sike!

有第三种方法可以找出实际出了什么问题吗？

从php docs尝试

function myErrorHandler($errno, $errstr, $errfile, $errline)
{
    if (!(error_reporting() & $errno)) {
        // This error code is not included in error_reporting, so let it fall
        // through to the standard PHP error handler
        return false;
    }

    switch ($errno) {
    case E_USER_ERROR:
        echo "<b>My ERROR</b> [$errno] $errstr<br />\n";
        echo "  Fatal error on line $errline in file $errfile";
        echo ", PHP " . PHP_VERSION . " (" . PHP_OS . ")<br />\n";
        echo "Aborting...<br />\n";
        exit(1);
        break;

    case E_USER_WARNING:
        echo "<b>My WARNING</b> [$errno] $errstr<br />\n";
        break;

    case E_USER_NOTICE:
        echo "<b>My NOTICE</b> [$errno] $errstr<br />\n";
        break;

    default:
        echo "Unknown error type: [$errno] $errstr<br />\n";
        break;
    }

    /* Don't execute PHP internal error handler */
    return true;
}
set_error_handler("myErrorHandler");

当error_get_last（）为null时该怎么办？
