php - 将图像编码为 Base64 无法正常工作

Question

if ( ! $this->upload->do_upload('course_profile_image'))
        {

            error($this->upload->display_errors(),TRUE,400);
        }else{
            $data = array('upload_data' => $this->upload->data());
            $filename=$data['upload_data']['file_name'];
            $pathinfo = 'dist/img/courseimage/'.$filename;
            $filetype = pathinfo($pathinfo, PATHINFO_EXTENSION);
            $filecontent = file_get_contents($pathinfo);

            try{
                $base64=rtrim(base64_encode($filecontent)); 

            }catch(Exception $e){
                error($e,TRUE,855);


            }
            $image = 'data: '.mime_content_type($pathinfo).';base64,'.$base64;  

它将图像转换为 base64，但当上传大尺寸图像时，它只需要其中的一半或部分图像。我将此 base64 存储到 mysql 数据库列类型文本中。

Change your database field type from text to mediumText because TEXT has only 64 KiB length so it not store your full base 64 code.
