What is the size limit of a post request?

Question

Sorry if this is duplicate,I would think it would be but couldn\'t find anything.

I have a flex application that I am posting data back to a php/mysql server via IE.

Answer 1

Also, in PHP.INI file there is a setting:

max_input_vars

which in my version of PHP: 5.4.16 defaults to 1000.

From the manual: "How many input variables may be accepted (limit is applied to $_GET, $_POST and $_COOKIE superglobal separately)"

Ref.: http://www.php.net/manual/en/info.configuration.php#ini.max-input-vars

Answer 2

By default, the post request has maximum size of 8mb. But you can modify it according to your requirements. The modification can be done by opening php.ini file (php configuration setting).

Find

post_max_size=8M  //for me, that was on line:771

replace 8 according to your requirements.

Answer 3

As David pointed out, I would go with KB in most cases.

php_value post_max_size 2K

Note: my form is simple, just a few text boxes, not long text.

(PHP shorthand for KB is K, as outlined here.)
