file_uploads=on/offmax_execution_time=30memory_limit=50M upload_max_filesize=20Mupload_tmp_dirpost_max_size=30M

Whether it is allowed to upload files via http
The maximum execution time allowed for the script, if it exceeds this time, an error will be reported
Set the maximum amount of memory that a script can allocate to prevent runaway scripts from occupying too much memory. This instruction only takes effect when the –enable-memory-limit flag is set during compilation.
The maximum size of files allowed to be uploaded, this command must be smaller than post_max_size
The temporary storage directory for uploaded files
Allow the post method to accept the maximum size

$_FILES array content is as follows:

$_FILES['myFile']['name']$_FILES['myFile']['type']$_FILES['myFile']['size']$_FILES['myFile'] ['tmp_name']$_FILES['myFile']['error']

The original name of the client's last file

Status code related to the file upload

$_FILES['myFile']['error']

Status code related to the file upload . [‘error’] was added in PHP version 4.2.0. The following is its description: (They became constants after PHP3.0)

UPLOAD_ERR_OK Value: 0UPLOAD_ERR_INI_SIZE value: 1UPLOAD_ERR_FORM_SIZE value: 2UPLOAD_ERR_PARTIAL value: 3UPLOAD_ERR_NO_FILE Value: 4Value: 5

       文件被上传结束后，默认地被存储在了临时目录中，这时您必须将它从临时目录中删除或移动到其它地方，如果没有，则会被删除。

       也就是不管是否上传成功，脚本执行完后临时目录里的文件肯定会被删除。

附：修改PHP上传文件大小限制的方法

1. 一般的文件上传,除非文件很小.就像一个5M的文件,很可能要超过一分钟才能上传完.

       但在php中,默认的该页最久执行时间为 30 秒.就是说超过30秒,该脚本就停止执行.

       这就导致出现 无法打开网页的情况.这时我们可以修改 max_execution_time

       在php.ini里查找

max_execution_time

       默认是30秒.改为

max_execution_time = 0

       0表示没有限制

2. 修改 post_max_size 设定 POST 数据所允许的最大大小。此设定也影响到文件上传。

       php默认的post_max_size 为2M.如果 POST 数据尺寸大于 post_max_size $_POST 和 $_FILES superglobals 便会为空.

       查找 post_max_size .改为

post_max_size = 150M

3. 很多人都会改了第二步.但上传文件时最大仍然为 8M.

       为什么呢.我们还要改一个参数upload_max_filesize 表示所上传的文件的最大大小。

       查找upload_max_filesize,默认为8M改为

upload_max_filesize = 100M

       另外要说明的是,post_max_size 大于 upload_max_filesize 为佳.
