Variables in PHP can be freely converted between types. For example, '2'+'3' gives 5. This function will return true for 3 and '3', but not for '3x'. Thus, it is very convenient to validate some parameters (like database identifiers). • function isFirstPartOfStr($str,$partStr) The name of this function is self-explanatory. • function validEmail($email) This function checks if the passed email has the correct syntax. It does not check whether that domain is valid or whether the mail account exists.

It is sometimes called "page" object among developers. This class contains methods that determine page ID, parse TypoScript templates, execute templates, process output and cache it. Also, TSFE is responsible for managing FE user object. TSFE is located in the class tslib_fe (exercise: see if you can guess the path to the file name). Normally, extensions do not call TSFE methods but use some TSFE class attributes. We will describe the most important attributes here: • additionalHeaderData This is an array where FE plugins can add HTML tags that should appear between
and on the page.
