请问一下 一对一关联时候怎样根据关联的 模型字段查询,例如用户表 有 id , account 等 -用户详细信息表 有 name,sex等,这是一对一关联,那怎样查出 account 含有 like 123 和 sex = 男的条目

请问一下 一对一关联时候怎样根据关联的 模型字段查询,例如用户表 有 id , account 等 -用户详细信息表 有 name,sex等,这是一对一关联,那怎样查出 account 含有 like 123 和 sex = 男的条目

<code>User::where('account', 'like', '%123%')->whereHas('UserInfo', function($query){
    $query->where('sex', '男');
})->first();</code>

手机撰写,上面的代码未经过编译。主要关键字是whereHas,具体的可以看文档

<code>User::where('account', 'like', '123')->where('sex', '男')->get();
</code>

不知道查询构造器可以不?

<code>DB::table('users')
            ->join('user_detail', 'users.id', '=', 'user_detail.user_id')
            ->where('account', 'like', '123')->where('sex', '男')
            ->get();</code>

嗯,你需要看看文档,来,给你个中文的~

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
