将SQL查询转储到Laravel中的屏幕

问题描述：

我正在尝试将实际的SQL查询输出到屏幕。我添加了以下路由：

I'm trying to output the actual SQL queries to the screen. I've added the following route:

// Display all SQL executed in Eloquent
Event::listen('illuminate.query', function($query)
{
    var_dump($query);
});

这主要是工作，但有些值出现问号：

This works mostly, but some values come out as question marks:

select DATE_FORMAT(DATE(`created_at`),'%b %d') as `date`, created_at, COUNT(*) as `count` 
from `contacts` 
where `created_at` > ? and `list_name` = ? or `list_name` = ? or `list_name` = ? 
group by `date` 
order by `created_at` asc

是否一个获得完整查询的方法来输出我动态添加的实际值，而不是无益的'？'字符？

Is there a way to get the full query to output the actual values I'm dynamically adding, rather than unhelpful '?' characters?

答

是的，您可以使用以下代码：

Yes, you can use this code:

Event::listen(
    'illuminate.query',
    function ($sql, $bindings, $time) {
        $sql = str_replace(array('%', '?'), array('%%', "'%s'"), $sql);
        $full_sql = vsprintf($sql, $bindings);

        file_put_contents(storage_path() . DIRECTORY_SEPARATOR . 'logs'
            . DIRECTORY_SEPARATOR . 'sql_log.sql', $full_sql . ";\n",
            FILE_APPEND);
    }
);

我在本地环境中将输出保存到文件中，当然可以在屏幕上显示此查询。

In mine I save output to file in local environment, you can of course display this query on screen.
