答案 0 :(得分：5)
检查php.ini中的upload_max_filesize，max_input_time，和 post_max_size
如果文件大小非常大，您可能还需要使用memory_limit。
答案 1 :(得分：1)
更改php.ini更改大小并测试脚本。（php.ini驻留在php安装目录中）
; Maximum allowed size for uploaded files.
upload_max_filesize = 2M
到
upload_max_filesize = Required_size M
答案 2 :(得分：1)
请检查服务器中的“max_input_time”选项是否太低，这可能就是PHP让你失望的原因。否则，它可能是与服务器/网络基础设施相关的问题：
echo ini_get('max_input_time');
如果从这里得到-1，很可能不是PHP会让你失望，而是循环中的其他东西。它可以是通往服务器的任何硬件，但很可能是服务器本身或服务器上的某些东西...
答案 3 :(得分：0)
对于大型文件，如果您不想处理配置服务器设置（特别是如果您使用的是共享主机或其他不能完全控制服务器的主机），一个可能的解决方案是将上传内容交给第三方服务。
例如，您可以让表单直接发布到Amazon S3（http://s3.amazonaws.com/doc/s3-example-code/post/post_sample.html）或使用Filepicker.io等服务
