PHP文件上传：读取原始文件数据

Question

As far as I know $_FILES["fieldname"]["size"] contains the file size after the file has been uploaded.

In Perl, you can read the raw file data very easy chunk-wise and that way determine if the file is too big before it has been fully uploaded.

Is there an easy way to do just the same in PHP?

Answer 1

You can change the max size in the php.ini config file, but it will affect all your file uploads :

upload_max_filesize 10M

If you're using a .htaccess file, you can also write like that :

php_value upload_max_filesize 10M

Take a look at the doc
