Cross-Site Scripting Tips
There are several platforms on which web pages are deployed and with thousands of people using different versions of software, scripting languages should be endowed with the proper set of tools that determines the proper set of scripts. Scripts for one platform may differ in form in another so a conversion method should be deployed to allow them to properly interface with each other. Though done behind the scenes, it is of utmost importance making the web experience more enjoyable with an example of the script below for reference.
PHP includes 3 functions that are built-in to help you with your cross-scripting tasks
- htmlspecialchars(str)
-htmlentities(str)
- strip_tags(str, allowed)
?>
The afore mentioned strings helps minimize the extensive need for code that would otherwise cause quite some hairfall, sent in by developers and users themselves who want to aid their fellow developers. The string “htmlspecialchars”, converts an entire string for passing onto HTML to convert brackets and other characters to recognized equivalents. The next one, “htmlentities” on the other hand, takes special characters that it finds and returns the equivalent escape values for it. The last, “strip-tags”, will strip any HTML tags that it encounters, ignoring the ones mentioned/enumerated in the allowed part of the string. These, strings also help a lot with preventing CSX attack that is one of the main security flaws that makes web pages prone to attack.
