本篇文章給大家分享的是有關(guān)laravel框架中怎么操作數(shù)據(jù)庫,小編覺得挺實(shí)用的,因此分享給大家學(xué)習(xí),希望大家閱讀完這篇文章后可以有所收獲,話不多說,跟著小編一起來看看吧。
laravel 數(shù)據(jù)庫配置
數(shù)據(jù)庫配置文件為項(xiàng)目根目錄下的config/database.php
//默認(rèn)數(shù)據(jù)庫為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, ],
發(fā)現(xiàn)都在調(diào)用env函數(shù),找到env文件,即根目錄下的.env文件,
打開修改配置參數(shù)
DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=homestead DB_USERNAME=homestead DB_PASSWORD=secret
修改為本地的數(shù)據(jù)庫信息:
DB_CONNECTION=mysql DB_HOST=localhost DB_PORT=3306 DB_DATABASE=laravel DB_USERNAME=root DB_PASSWORD=123456
laravel 操作數(shù)據(jù)庫
建立student控制器,控制器代碼
namespace App\Http\Controllers; use Illuminate\Support\Facades\DB; class StudentController extends Controller { //添加 public function addstudent(){ $student = DB::insert('insert into student(name,age,gender) values(?,?,?)',['張三',12,2]); var_dump($student);//成功返回bloo值true } //獲取 public function getall(){ // $student = DB::select('select * from student'); $student = DB::select('select * from student where id>?',[1]); return $student;//數(shù)組 } //修改 public function updstudent(){ $student = DB::update('update student set age= ? where name=?',[10,'張三']); var_dump($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會(huì)報(bào)錯(cuò):
(1/1) UnexpectedValueException
The Response content must be a string or object implementing __toString(), "boolean" given.
