【问题描述】：
我一直在处理客户的管理面板（一家摄影公司将图片上传到客户的画廊），当我担任网络开发人员时，它只允许他上传 30 张图片 ，即使有 100 个文件上传框。只需将 for 循环更改为运行 100 次，即可解决此问题。这解决了这个问题。
但是最近，我的客户连代码都没碰，只能上传19张图片..我没有改这个表格，他之前上传了40多张图片，所以我不太清楚了解可能发生的事情。我一遍又一遍地检查代码，但似乎无法确定问题所在。这可能是服务器端，因为我最近从他的旧开发者的主机转移到了我的 hostgator 帐户。也许在htaccess的东西？我添加这个是因为 图像标签的更新，而不是 图像本身（我也找不到它上传，在它发布后，但我的浏览器显示它正在上传）
这是编辑库代码本身，如果它对问题有任何帮助：

如果我可以提供任何其他有助于找到解决方案的信息，我可以直接发布。这个问题真的让我很头疼，我的客户需要他的画廊运行！让我希望我可以自己编写代码并在他以前的开发人员之前到达那里。谢谢大家！
【问题讨论】：
-
运行 phpinfo() 并检查内存限制。尝试使用 .htacces 文件将其设置为 128M。
-
容量从 40+ 减少到 19 张图片肯定是由于移动到另一台服务器造成的。但是您的客户上传的尺寸是多少？拥有大量大图像的上传速度可能会非常慢，并导致超时或因服务器限制而停止。你有什么错误吗？您应该查看 PHP 配置中的 upload_max_filesize、post_max_size 和 max_input_time。您可以在 php.ini、.htaccess 甚至脚本本身中设置这些参数 - 但取决于您的主机。
-
嗯，我确定这与图像大小或超时无关，因为我已经尝试上传非常小的图像，并且在一批 19 之后还上传了额外的图像，所以我知道这只是一个单一的图像上传。这让我感到困惑并让我思考，这真的是服务器问题吗？：在以前上传了 30 多张图片的画廊上，我删除了 图片 26，并尝试用不同的图像重新上传它，但它没有用。我对 image 17 做了同样的事情，但它奏效了。所以我不知道...谁能看到我遗漏的东西？？
-
请发布您收到的错误消息。
-
内存限制设置为 256M :/
