This is a PHP library called AntiXSS, which is designed to prevent cross-site scripting (XSS) attacks. The library provides a set of functions to sanitize user input and protect against XSS vulnerabilities.
The library is maintained by Lars Moelleken and is available on Packagist, a popular PHP package repository. The library is licensed under the MIT License.
The library provides several functions to sanitize user input, including:
`xss_clean()`: This function takes a string as input and returns the sanitized string.
`filter_input()`: This function takes a string as input and returns the sanitized string.
The library also provides a set of configuration options to customize the sanitization process, including:
`$_never_allowed_regex`: This is a list of regular expressions that are never allowed to be replaced.
`$_never_allowed_call`: This is a list of call statements that are never allowed.
The library is designed to be used in conjunction with other security measures, such as Content Security Policy (CSP) and HTML Purifier.
The library has a test suite that covers various scenarios, including:
Sanitizing user input
Handling edge cases
Testing the library's configuration options
The library is compatible with PHP 7.0 and later versions.
