PHP: whats the total length of a post global variable?

Question

I was wondering if anybody knows the total length that a post global could be. e.g:

$_POST[\'formInput\'] = \"hello world, how long can i be?\";

Answer 1

Check your php.ini for post_max_size. This is typically about 8mb by default, but if you're on shared-hosting, it could definitely vary.

; Maximum size of POST data that PHP will accept.
post_max_size = 8M

You'll have to use $_POST if you wish to send large amounts of data to the server. For further study, I'd suggest checking out POST Method Uploads in the documentation.
