Synopsis

PHP Input Variables Exceeded

Description

By default, PHP accepts a maximum of 1000 variables in a request. If there are more input variables than specified, an E_WARNING is issued, and further input variables are truncated from the request depending on server configuration and application code, this can have various impacts such as bypassing function call.

Solution

Disable all notice, warning and error displaying. Configure the application to log such messages in a file. A code review is also necessary to check the impact it may have on the application.
