PHPExcel拡張子をYii2プロジェクトで使用しましたが、PHPExcelオブジェクトのコンポーネントを作成しましたが、このコンポーネントは「読み取り不可能なコンテンツ」Excelファイルをエクスポートします。PHPExcelエクスポート「読み込み不可能なコンテンツ」Excelファイルin yii2
- PHPExcel - .xlsx file downloads unreadable content
- PHPExcel creates 'unreadable content'
- https://stackoverflow.com/questions/32103447/excel-found-unreadable-content-with-phpexcel
- PHPExcel unreadable content
私は "読めないコンテンツ" エクセル以下の行き方：
は、私はこれらのリンクから、この問題のためにすべての可能な解決策を読んだことがありますファイル：
