What is the size limit of a post request?

Does $_POST when used in conjunction with forms in PHP have a size limit? Obviously there must be some restrictions with $_GET seeing as most browsers will start to complain at ~250 characters (or something like that) and data could be lost, obviously this restraint doesn't apply to $_POST.

I could test it myself but thought it might be quicker to simply ask here. If I had a simple form with a textarea, how much data could I enter before I ran into problems?

Answer 1

That depends on the value of the PHP configuration directive POST_MAX_SIZE which is usually set to 8 MB (~8 million characters).

Answer 2

Yes it has limitation, you can set the limit from several place:

1., in php.ini

post_max_size="8M"

2., from the .htaccess file, if you have

php_value post_max_size 8M 

3., from php side,

ini_set('post_max_size',"8M")
