我需要上傳文件並將上傳的文件作爲附件發送到郵件中並從網頁下載文件。該文件的內容使用mediumblob數據類型存儲在數據庫中。上傳文件和發送文件作爲附件工作正常。當我下載的文件內容不是可讀的格式。內容是顯示爲上傳sendfile文件作爲附件並下載php中的文件

下面是代碼
upload.php的

如果添加上面的代碼,問題也是一樣的。上傳的文件讀取內容,而下載的文件讀取內容如下。 UEsDBBQABgAIAAAAIQDfpNJsWgEAACAFAAATAAgCW0NvbnRlbnRfVHlwZXNdLnhtbCCiBAIooAAC AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA – user6582683
因爲你已經base64編碼的文件,我認爲這是這裏唯一缺少的是BASE64 DECODE –
和關閉過程需要恢復chunk_split;)通過去除新線 –
