// This function looks for text including markup and
|

// applies tidy's repair function to it.
|
|
// Tidy is a HTML clean and
|
|
// repair utility, which is currently available for PHP 4.3.x and PHP 5 as a
|
|
// PECL extension from http://pecl.php.net/package/tidy, in PHP 5 you need only
|
|
// to compile using the --with-tidy option.
|
|
// If you don't have the tidy extension installed or don't know, you can enable
|
|
// or disable this filter, it just won't have any effect.
|
|
// If you want to know what you can set in $tidyoptions and what their default
|
|
// values are, see http://php.net/manual/en/function.tidy-get-config.php.
