在线生产环境中，Eloquent模型中的id周围的引号是必需的，但在本地主机上无法正常工作。

我有一个查询，在我的生产环境安装中，在'where'方法中需要在"id"周围加上引号，否则返回没有结果。在我的本地安装中，正好相反。如果我使用引号，它就无法正常工作。

生产环境：

'invoices' => Auth::user()->invoices->where('paid', "0")

本地主机：

'invoices' => Auth::user()->invoices->where('paid', 0)

这真的很奇怪，我真的不想每次从github部署时都要去更改这个。这是常见的问题吗？我似乎找不到任何相关资料。

我将列出一些Laravel查询日志：

在带引号的整数的本地安装中（不起作用）：

Array ( 
    [0] => Array ( 
        [query] => select * from `users` where `users`.`id` = ? limit 1 
        [bindings] => Array ( 
            [0] => 1 
        ) 
        [time] => 10.49 
    )
    [1] => Array ( 
        [query] => select * from `invoices` where `invoices`.`user_id` = ? and `invoices`.`user_id` is not null 
        [bindings] => Array ( 
            [0] => 1 
        ) 
        [time] => 1.39 
    ) 
)

在不带引号的整数的本地安装中（起作用）：

Array (     
    [0] => Array ( 
        [query] => select * from `users` where `users`.`id` = ? limit 1 
        [bindings] => Array ( 
            [0] => 1 
        ) 
        [time] => 0.84 
    ) 
    [1] => Array ( 
        [query] => select * from `invoices` where `invoices`.`user_id` = ? and `invoices`.`user_id` is not null 
        [bindings] => Array ( 
            [0] => 1 
        ) 
        [time] => 1.15 
    ) 
)

在不带引号的整数的生产安装中（不起作用）：

Array ( 
    [0] => Array ( 
        [query] => select * from `users` where `users`.`id` = ? limit 1
        [bindings] => Array ( 
            [0] => 1 
        ) 
        [time] => 2.3 
    ) 
    [1] => Array ( 
        [query] => select * from `invoices` where `invoices`.`user_id` = ? and `invoices`.`user_id` is not null 
        [bindings] => Array ( 
            [0] => 1 
        ) 
        [time] => 0.67 
    ) 
)

在带引号的整数的生产安装中（起作用）：

Array ( 
    [0] => Array ( 
        [query] => select * from `users` where `users`.`id` = ? limit 1 
        [bindings] => Array ( 
            [0] => 1 
        ) 
        [time] => 0.88 
    ) 
    [1] => Array ( 
        [query] => select * from `invoices` where `invoices`.`user_id` = ? and `invoices`.`user_id` is not null 
        [bindings] => Array ( 
            [0] => 1 
        ) 
        [time] => 0.81 
    ) 
)

解决方案：

原来我在服务器上没有激活mysqlnd驱动程序。激活它解决了这个问题。
