Which of the following would you use to validate incoming data from a web form? (choose three)?


[5854,5858,5860]
Correct: --> filter_* functions --> ctype_* functions --> preg_* functions

The key word in the question is "validate" – some of the options to choose from are great ways to sanitize data, but not to validate it. The three answers are all great ways to work with incoming data which you should be familiar with: http://www.php.net/manual/en/book.filter.php http://www.php.net/manual/en/book.ctype.php http://www.php.net/manual/en/ref.pcre.php
