Filter Laravel Package
joomla/filter
Joomla Filter provides input sanitization and filtering utilities for PHP apps. Use InputFilter to allow/block specific HTML tags and attributes, and OutputFilter for safe output helpers like URL-safe strings. Composer installable, lightweight, framework-ready.
The Filter Package 
Installation via Composer
Add "joomla/filter": "~3.0.*@dev" to the require block in your composer.json and then run composer install.
{
"require": {
"joomla/filter": "~3.0"
}
}
Alternatively, you can simply run the following from the command line:
composer require joomla/filter "~3.0"
If you want to include the test sources, use
composer require --prefer-source joomla/filter "~3.0"
Note that the Joomla\Language package is an optional dependency and is only required if the application requires the use of OutputFilter::stringURLSafe.
Upgrades from 1 to 2
Note the InputFilter static class constants have been renamed:
| Before | After |
|---|---|
| InputFilter::TAGS_WHITELIST | InputFilter::ONLY_ALLOW_DEFINED_TAGS |
| InputFilter::TAGS_BLACKLIST | InputFilter::ONLY_BLOCK_DEFINED_TAGS |
| InputFilter::ATTR_WHITELIST | InputFilter::ONLY_ALLOW_DEFINED_ATTRIBUTES |
| InputFilter::ATTR_BLACKLIST | InputFilter::ONLY_BLOCK_DEFINED_ATTRIBUTES |
The public property InputFilter::tagBlacklist has been renamed to InputFilter::blockedTags. Similarly
InputFilter::attrBlacklist has been renamed to InputFilter::blockedAttributes
All code usage of these properties remains unchanged.
