file-upload - PHP 文件上传大于 upload_max_filesize 和错误

Question

如果上传到我的 Web 服务器的文件大于 php upload_max_filesize，我该如何捕获错误？

我的问题类似于so/large-file-upload-errors-with-php尽管我的内存限制设置为 512M，所以该问题所使用的分辨率对我没有帮助。

例如，我正在尝试上传一个 6.9MB 的文件，而我的 upload_max_filesize = 6M。我的脚本基本上只是停止执行，我不知道在哪里或为什么。另外，我打开了错误报告。

我还应该注意，文件 <6MB 我可以使用以下代码正确上传和处理:

if(isset($_FILES['file']['name']) and !empty($_FILES['file']['name'])){

    $info = pathinfo($_FILES['file']['name']); 
    $ext = $info['extension'];
    //verify file is of allowed types 
    if(Mimetypes::isAllowed($ext)){
        if(filesize($_FILES['file']['tmp_name']) <= AttachmentUploader::$maxFilesize){              
            $a = new AttachmentUploader();      //for file uploading 
            if($a->uploadFile($_FILES['file'], 'incident', $_POST['sys_id'])){
                header("location: ".$links['status']."?item=incident&action=update&status=1&place=".urlencode($links['record']."id=".$_POST['sys_id']));            
            }else{
                header("location: ".$links['status']."?item=incident&action=update&status=-1&place=".urlencode($links['record']."id=".$_POST['sys_id']));           
            }

        }else{      
            $errors[] = 'The file you attempted to upload is too large.  0.5MB is the maximum allowed size for a file.  If you are trying to upload an image, it may need to be scaled down.';
        }
    }else{
        $errors[] = 'The file you attempted to upload is not allowed.  Acceptable extensions: jpg, gif, bmp, png, xls, doc, docx, txt, pdf';
    }
}else{
    $errors[] = 'Please attach a file.';
}

我的 php.ini 设置:

;;;;;;;;;;;;;;;;;;;
; Resource Limits ;
;;;;;;;;;;;;;;;;;;;

max_execution_time = 7200     ; Maximum execution time of each script, in seconds
memory_limit = 512M  ; Maximum amount of memory a script may consume (8MB)


;;;;;;;;;;;;;;;;
; File Uploads ;
;;;;;;;;;;;;;;;;

; Whether to allow HTTP file uploads.
file_uploads = On

; Temporary directory for HTTP uploaded files (will use system default if not
; specified).
upload_tmp_dir = /tmp

; Maximum allowed size for uploaded files.
upload_max_filesize = 6M

Answer 1

错误在 $_FILES['userfile']['error'] 中。您只需检查此值是否为 UPLOAD_ERR_INI_SIZE 即可检测文件是否大于 php.ini 中定义的最大大小。
