这个问题 ... 首先先确定你的改动已经生效了 ...
<?php
echo ini_get( 'post_max_size' );
然后确定设定的 memory_limit
> post_max_size
> upload_max_filesize
...
另外说 ... 手册里面有写下面的文字 ...
Note: PHP allows shortcuts for bit values, including K (kilo), M (mega) and G (giga). PHP will do the conversions automatically if you use any of these. Be careful not to exceed the 32 bit signed integer limit (if you’re using 32bit versions) as it will cause your script to fail.
如果说上面两步都确定了还是不行的话 ... 修改 post_max_size 到小一点的值比如 1024M 这样 ...
