note 118269 deleted from function.intval by cmb

Note Submitter: Er.ellison ---- i guess one of the important usage of intval is in links , because : imagine that u have a function that uses get method (for example an integer id ) to retrieve the data from DB , so for example if you get " id=58 " in your link and put that in u'r function that retrieves data from DB , that's fine , it works well but what if some body put the " id=58djkdjsbvjkdsbvjkdbs " in the link ON PURPOSE ! in such situation and condition he will get an Database error because u'r function retrieves Data from DB so it good to be use intval in such situations because if u use that u gonna be sure that what ever that passes from u'r DB related function is just a integer , No text and any strange character ! let me show u by example $id = 12dfjgdfjgnd; echo $id // output will be : 12dfjgdfjgnd echo intval($id) // output will be : 12
