php框架laravel excel包使用教程介绍
Laravel是一套简洁、优雅的PHP Web开发框架(PHP Web Framework)。它可以让你从面条一样杂乱的代码中解脱出来;它可以帮你构建一个完美的网络APP了,下面我们来看看laravel excel包使用教程
laravel中excel插件的安装
在composer中引入laravel excel的包
"maatwebsite/excel": "1.*"
在位于laravel/app/config下编辑app.php文件,在providers数组中添加以下值
'Maatwebsite\Excel\ExcelServiceProvider',
在同文件中找到aliasses数组添加以下值
'Excel' => 'Maatwebsite\Excel\Facades\Excel',
执行composer install 或 composer update命令.
laravel excel的配置
在位于laravel/vendor/maatwebsite/excel/src/config下一些对于插件的一些配置项
config.php > 对excel和表全局的一些设置
csv.php > 对导入导出csv文件的设置
export.pho > 对打印出文件内容的一些设置
import.php > 对导入excel文件的设置
laravel excel的简单使用
在之前的准备工作都做好了以后我们就可以用excel插件了
导出excel
$rows = array( array( 'id' => 1, 'name' => 'marlon' ) );
Excel::create($name, function($excel) use ($rows) {
$excel->sheet('当天报名', function($sheet) use ($rows) {
$sheet->fromArray($rows);
});
})->store('xls', storage_path('excel'));
由于在php闭包中无法拿到闭包外的变量,所以需要用use把$rows引入进去,在最后的链式调用的store中所传的参数就是所需excel的格式和要保存到服务器的位置,此为绝对路径.
在这个地方store()方法为存储,相对应的还可以使用download()方法来直接下载,至于export方法笔者还没搞懂用处是什么
导入excel
Excel::load(Input::file('excel'), function($reader) {
//获取excel的第几张表
$reader = $reader->getSheet(0);
//获取表中的数据
$results = $reader->toArray();
//在这里的时候$results 已经是excel中的数据了,可以再这里对他进行操作,入库或者其他....
});

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
