Question

我在laravel 5中完成了导入，但在导出文件时遇到了一些问题。代码不正确，不提供任何逻辑。我尝试过类似文档

public function exportData(Test $test,Excel $excel){
  $test=$test->all();
    Excel::create('Test excel', function($test) {

    $test->sheet('sheet1', function($sheet) {

        $sheet->setOrientation('landscape');

    });

})->export('xls');
    }

如何从mysql导出csv文件？我正在使用＆＃34; maatwebsite / excel＆＃34;：＆＃34; ~2.0.0＆＃34;封装

Answer 1

您可以在Laravel中使用INTO OUTFILE

public function exportData($file_name) {

          $file = public_path()."/downloads/".$file_name; //CSV file is store this path

          $query = sprintf("select * from tests INTO OUTFILE '%s' FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\n'",$file);

         \DB::connection()->getpdo()->exec($query);
    }

Answer 2

您可以考虑使用league/csv包。他们有an example of exporting a database query to CSV。在您的情况下，它看起来像：

public function exportData() {
    // get the data
    $data = Test::all();

    // get a Writer object for writing to CSV
    $csv = League\Csv\Writer::createFromFileObject(new SplTempFileObject());

    // add the data to the writer
    $csv->insertAll($data);

    // output the file
    $csv->output('testdata.csv');
}
