php文件上传的大小

Question

do we have any size issue with the file uploads that we perform in php using $_file[upload][name]? is there any restriction for the file upload using this ??? juz need to know ..

Answer 1

In your php.ini

; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 2M

and (added after suggestions from others below)

; Maximum size of POST data that PHP will accept.
; http://php.net/post-max-size
post_max_size = 8M

Answer 2

You can limit maximum file uploaded size (you should change appropriate directives in your php.ini file). There are no other ways to limit uploaded file size.

upload_max_filesize = 1M //Maximum size of uploaded file
max_post_size = 1M //Maximum size of whole POST request

Answer 3

You can also change limits in .htaccess file:

php_value upload_max_filesize 10M
php_value post_max_size 20M

Answer 4

是的，这受到上载最大文件大小的限制，并且更普遍地受到php.ini中post_max_size设置的限制。
