I took a look at this page (and all the functions referenced
therein).  While there must be a use for these functions
otherwise they wouldn't have been included in PHP, I'm at
a total loss as to why anyone would ever use them.  Why
wouldn't you just call the function (or do whatever) yourself?
Could anyone offer some insight?
