PHP如何查找允许的最大POST数据？

Question

In PHP, is there a quick way to find the maximum allowed size of POST data for any server configuration that my script is run on?

For example, $max_post_length = $_SERVER['maxpost']; or something. Perhaps it would return 0 for 'no limit'...any ideas?

Answer 1

使用ini_get 。

ini_get('post_max_size');

Answer 2

Try this:

echo ini_get('post_max_size');

Or translate it to bytes:

echo (int)(str_replace('M', '', ini_get('post_max_size')) * 1024 * 1024);
