上传大文件和超时 php 上传

Question

客户的站点上传文件，但如果这些文件很大，则会返回超时错误503 Service Unavailable。

hopedagem 将超时时间限制在300秒，请问有没有什么方法可以通过js或者相关的方式上传不超时？ 上传的是视频。

The hosting server does not allow time out editing.

Answer 1

转到php.ini 文件并根据您的要求更改值。

upload_max_filesize

默认情况下，此值为 2M。我们需要将其增加到我们要上传的单个文件的最大大小。

最大输入时间

这将设置允许脚本解析输入数据的最长时间（以秒为单位），例如 POST 和 GET。计时从服务器调用 PHP 的那一刻开始，到执行开始时结束。这将包括填充$_FILES superglobal。

memory_limit

这设置了 PHP 脚本在执行期间允许使用的内存量。将此设置为大于“post_max_size”的值，以便 PHP 脚本可以加载和处理上传的文件。

post_max_size

它定义了 PHP 将接受的 POST 数据的最大大小。此值应大于“upload_max_filesize”。

ma​​x_execution_time

脚本在其输入被解析后允许运行的时间。这将包括对文件本身的任何处理。

如果您遇到与内存相关的错误，请关闭输出缓冲，要考虑的 PHP 配置指令是“output_buffering”

output_buffering = Off

我还添加了上述配置的参考，您可以找到更多详细信息here

Answer 2

您需要更改 php.ini 中的一些设置：

upload_max_filesize = 500M 
;or whatever size you want

max_execution_time = 1000
; also, higher if you must - sets the maximum time in seconds
