本文实例讲述了laravel框架数据库配置及操作数据库。分享给大家供大家参考，具体如下：
laravel 数据库配置
数据库配置文件为项目根目录下的config/database.php

//默认数据库为mysql'default' => env('DB_CONNECTION', 'mysql'), 'mysql' => ['driver' => 'mysql','host' => env('DB_HOST', '127.0.0.1'),'port' => env('DB_PORT', '3306'),'database' => env('DB_DATABASE', 'forge'),'username' => env('DB_USERNAME', 'forge'),'password' => env('DB_PASSWORD', ''),'unix_socket' => env('DB_SOCKET', ''),'charset' => 'utf8mb4','collation' => 'utf8mb4_unicode_ci','prefix' => '','strict' => true,'engine' => null,], |
发现都在调用env函数，找到env文件，即根目录下的.env文件，
打开修改配置参数

DB_CONNECTION=mysqlDB_HOST=127.0.0.1DB_PORT=3306DB_DATABASE=homesteadDB_USERNAME=homesteadDB_PASSWORD=secret |
修改为本地的数据库信息：

DB_CONNECTION=mysqlDB_HOST=localhostDB_PORT=3306DB_DATABASE=laravelDB_USERNAME=rootDB_PASSWORD=123456 |

namespace App\Http\Controllers;use Illuminate\Support\Facades\DB;class StudentController extends Controller{ //添加 public function addstudent(){ $student = DB::insert('insert into student(name,age,gender) values(?,?,?)',['张三',12,2]); var_dump($student);//成功返回bloo值true } //获取 public function getall(){// $student = DB::select('select * from student'); $student = DB::select('select * from student where id>?',[1]); return $student;//数组 } //修改 public function updstudent(){ $student = DB::update('update student set age= ? where name=?',[10,'张三']); var_dump($student);//成功返回bloo值true } //修改 public function delstudent(){ $student = DB::delete('delete from student where id=?',[10]); var_dump($student); }} |
注意 laravel中return true会报错：
(1/1) UnexpectedValueException
The Response content must be a string or object implementing __toString(), "boolean" given.
希望本文所述对大家基于Laravel框架的PHP程序设计有所帮助。
