Laravel 查询生成器绑定

Question

有人可以解释一下为什么在 Laravel 中第一个代码有效而第二个代码无效。

$data = DB::select("SELECT * FROM people WHERE name LIKE '%john%'");


$data = DB::select("SELECT * FROM people WHERE name LIKE '?'", ['%john%']);

Answer 1

如果您要使用查询生成器，您可以这样做：

$data = DB::select("SELECT * FROM people WHERE name LIKE :name", ['name' => "%john%"]);

不过最好用Eloquent:

People::where('name', 'like', "%john%")->get();
