在PHP设置中，memory_limit> upload_max_filesize? [英] In PHP settings, should memory_limit > upload_max_filesize?

问题描述

我正试图允许用户上传大文件(64MB)，并计划将upload_max_filesize更改为64MB.

I'm trying to allow users to upload large files (64MB) and am planning to change upload_max_filesize to 64MB.

但是，我还应该将memory_limit更改为64MB或更大吗?

However, should I also change memory_limit to 64MB or larger?

memory_limit是否已连接到upload_max_filesize?

推荐答案

否，没有必要.

PHP具有不同的POST读取器和处理程序，具体取决于请求的内容类型.如果是"multipart/form-data"(用于发送文件的内容)，

PHP has different POST readers and handlers depending on the content type of the request. In case of "multipart/form-data" (what is used for sending files), rfc1867_post_handler acts as a mixed reader/handler. It populates both $_POST and $_FILES. What goes into $_POST counts towards the memory limit, what goes into $_FILES also counts.

但是，$_FILES只是有关文件的元数据，而不是文件本身.这些只是写入磁盘，因此不计入内存限制.

However, $_FILES has just meta-data about the files, not the files themselves. Those are just written into the disk and hence don't count towards the memory limit.
