PHP上传错误2（最大文件大小）

我们的Mahara网站存在问题，无论大小，我们都无法上传任何文件

深入研究代码，$\u文件数组将返回以下内容：

Array
(
    [userfile] => Array
    (
        [name] => Array
            (
                [0] => file.jpg
            )

        [type] => Array
            (
                [0] => 
            )

        [tmp_name] => Array
            (
                [0] => 
            )

        [error] => Array
            (
                [0] => 2
            )

        [size] => Array
            (
                [0] => 0
            )

    )

)

现在，我已经检查了我们的php ini设置（并检查它们是否应用于phpinfo（））：

我们有：

立柱最大尺寸4000M

上传最大文件大小4000M

文件上传到

max_文件上传20

内存限制128M

最大执行时间600

上传\u tmp\u目录“无值”

我不确定upload_tmp_dir是否应该有什么内容，但我们在这台服务器上运行了两个网站，另一个网站上传文件没有问题，所以我假设这不是问题所在

据我所知，我们的服务器设置很好

在表单的HTML中：

<div id="instconf_artefactid_upload_container" class="fileupload">
  <input type="hidden" name="instconf_artefactid_uploadnumber" id="instconf_artefactid_uploadnumber" value="1"><input type="hidden" name="instconf_artefactid_upload" id="instconf_artefactid_upload" value="0">
  <input type="hidden" name="MAX_FILE_SIZE" value="4194299904">
  <div id="instconf_artefactid_upload_messages"></div>

  <table class="fileuploadlicense"><tbody></tbody></table>
  <div class="uploadform">
    <label for="instconf_artefactid_userfile">Upload file</label>
      <span id="instconf_artefactid_userfile_container"><input type="file" class="file" id="instconf_artefactid_userfile" name="userfile[]" multiple="" size="20"></span>
      <span id="instconf_artefactid_userfile_maxuploadsize">(Maximum upload size 3.9GB)</span>

  </div>

  <div id="file_dropzone_container" class="instconf_artefactid">
      <div id="fileDropzone" class="dropzone-previews" style="display:none;">
        <div class="dz-message">Drop files here to upload</div>
      </div>
  </div>
  <div class="uploadform">
    <div id="instconf_artefactid_uploadsubmit_container">

      <noscript>&amp;lt;input type="submit" class="submit" name="instconf_artefactid_upload" id="instconf_artefactid_upload" value="Upload" /&amp;gt;</noscript>
    </div>
  </div>

</div>

上传文件
（最大上载大小3.9GB）
把文件放在这里上传
&；书信电报；输入type=“submit”class=“submit”name=“instconf\u artifactid\u upload”id=“instconf\u artifactid\u upload”value=“upload”/&；燃气轮机；

因此，表单的最大文件大小为4194299904，但无论我尝试上传什么文件，即使是大约100字节的1像素图像，我也会遇到同样的错误

在CentOS服务器上运行的Mahara的所有实例上似乎都是一样的，但在我的Windows localhost上，上传工作正常

有人知道这可能是什么原因吗

谢谢

您是否尝试过降低限额以防万一？在32位平台上，保存4 GB字节所需的整数超过了PHP_INT_MAX。啊哈，我把它改为2000M，这样就行了。谢谢这是一个32位系统无法克服的缺点吗？或者有没有办法将最大大小增加到该限制之上？一般来说，解决此类限制的方法是。。。64位体系结构；-）有趣的是，我刚刚检查了我们的centos框，它是64位哦。。。这表明您已经达到了其他硬编码限制：（你有没有试过降低限制以防万一？在32位平台上，容纳4 GB字节所需的整数超过了PHP_INT_MAX。啊哈，我把它改为2000M，这样就行了。谢谢。这只是一个在32位系统上无法克服的lmiitation？还是有没有办法将最大大小提高到该限制之上？一般来说解决这些限制的方法是…64位体系结构；-）有趣的是，我刚刚检查了centos框，它是64位的哦…这表明您达到了其他硬编码限制：(
