note 23386 deleted from function.settype by googleguy

Note Submitter: djworld at php dot net ---- Usually it won't be necessary to use this function, but some times you need to be sure the variables are of some kind. For example, if you send a number to a database query from a variable passed by GET or POST, you may get sure it's a number by doing SetType ($var, 'integer'); so you can avoid security holes if it isn't a number and you don't need to addslashes() it, or for example, if you need to be sure that a number won't have any decimals after rounding it, you may do the same and as it will be an integer, it won't contain decimals.
