我的 PHP Web 应用程序需要将文件(大小约为 2.5 到 3 GB)上传到服务器.这将如何影响以下指令?

My PHP web application requires files (about 2.5 to 3 GB in size) to be uploaded to the server. How will this impact on following directives ?

在我的案例中需要什么值?

what are the required values in my case?

  • post_max_size
  • upload_max_filesize
  • memory_limit

非常感谢您的帮助.

推荐答案

  1. post_max_size 应该是 3G

upload_max_filesize 应该是 3G

memory_limit 视情况而定！！！您将如何处理该文件.如果您要操作文件或执行其他内存密集型作业，则需要设置一个上限.如果您不想设置最大限制，您可以随时将其设置为 -1.该值与文件大小无关，而与脚本处理作业所需的物理内存大小有关.

memory_limit depends!!! what you are going to do with the file. If you are going to manipulate the file or do other memory intensive jobs, then you will need to set a high limit. If you don't want to put a maximum limit, you can always set it to -1. This value doesn't have to do much with the size of the file, but rather with the size of the physical memory your script needs to handle the job.

对于前两个，它是您希望上传的最大文件大小，后缀为简写字节值.对于KB应该是K，MB应该是M，GB应该是<代码>G, ...

For the first two, it is the maximum file size you expect to be uploaded, suffixed with a short hand byte value. For KB should be K, MB should be M, GB should be G, ...
