config_clean()

Description

Utility function to "clean" the passed $config. Cleaning consists of two parts:
Suppressing really simple XSS attacks by refusing to allow strings
containing the characters "<script" in upper, lower or mixed case.
Unescaping instances of "'" and '"' that have been escaped by the
lovely magic_quotes_gpc facility, if it's on.

Parameters

ColumnTypeDefaultDescription
$config
