AntiXSS is a class for use with PHP 5+ that helps to reduce XSS (cross-site scripting) vulnerabilities by automatically encoding output to behave only as intended.


  • PHP5 and above
  • mb_string PHP extension


  1. Make sure the mb_string extension is available with your PHP installation. If you are using Apache on Windows, this can most likely be done by adding (or un-commenting) a line in your php.ini file. On other platforms, you may need to recompile PHP. See [1] for more information.
  2. To make the code available to your program, include the owasp.antixss.php file, using a line like this: require_once "/path/to/owasp.antixss.php";
  3. It is not necessary to instantiate the class, though you may if you wish. Instead, make calls using the Scope Resolution Operator (::), like this: echo AntiXSS::HTMLEncode($myOutput);



Hello, <php echo AntiXSS:HTMLEncode($nameOfMyUser); ?>!


... alert(myFunction('<?php echo AntiXSS:JavaScriptEncode($myVariable); ?>'); ...


...<?php echo AntiXSS::URLEncode($myQueryStringValue); ?> ...


<myelement myattribute="<?php echo AntiXSS::XMLAttributeEncode($myAttributeValue); ?>"><?php echo AntiXSS::XMLEncode($myElementValue); ?></myelement >
