git larav-excel处理excel的包

例子

// 选中第一个Sheet, 这样第一行当做属性名
Excel::selectSheetsByIndex(0)->load($cretae_path, function ($reader) use (&$errorRow, &$successCount, &$rowsCount, &$user_id, &$item, &$file_url, &$history, $entry_way_id) {
  //获得所有数据
  $data = $reader->all()->toArray();
}

安装

Require this package in your composer.json and update composer. This will download the package and PHPExcel of PHPOffice.

"maatwebsite/excel": "~2.1.0"

After updating composer, add the ServiceProvider to the providers array in config/app.php

Maatwebsite\Excel\ExcelServiceProvider::class,

You can use the facade for shorter code. Add this to your aliases:

'Excel' => Maatwebsite\Excel\Facades\Excel::class,

The class is bound to the ioC as excel

$excel = App::make('excel');

To publish the config settings in Laravel 5 use:

php artisan vendor:publish --provider="Maatwebsite\Excel\ExcelServiceProvider"

This will add an excel.php config file to your config folder.
