According to PHP official manual   It is used to converts a string to an array. If the optional split_length parameter is specified, the returned array will be broken down into chunks with each being split_length in length, otherwise each chunk will be one character in length. FALSE is returned if split_length is less than 1 PHP to ASP Let's first look at how you can pass data from PHP to ASP using WDDX. You create a WDDX packet by first serializing data into a WDDX packet and then presenting it. WDDX can convert most variable types that applications use, such as strings, integers, and arrays. After a variable has been converted to a WDDX variable type, it is ready for another application to pick up. PHP has WDDX support built in, so you don't need to modify your PHP.ini file to start using WDDX. A ....! <?php echo 'Hello World'; ?> ....! Calculate the md5 hash of a string.

Cross-site scripting (XSS) is a security exploit in which the attacker inserts malicious coding into an link that appears to be from a trustworthy source. When someone clicks on the link, the embedded programming is submitted as part of the client's Web request and can execute on the user's computer, typically allowing the attacker to steal information. Web forms that dynamically return an error message including user input data make it possible for attackers to alter the HTML that controls the behavior of the form and/or the page. Attackers....!
