note 95468 added to function.is-int

An interesting thing I discovered is that is_int() may not work if checking a string for only numeric values. As a for instance, I have a form that requests user input, and the field name is $search. When the user clicks the "submit" button, the form then runs through a couple of verifications, including one that checks whether they entered only numbers in the search (this is for those who specify searching by only a receipt number), not a hex code or some other alpha-numeric term. When running ... if (is_int($search)) {echo "Say something nice."; }else{ echo "Oops! You're no mathematician!";} ... the script did not work. It read all entries, whether purely numeric or alpha-numeric, as non-integers. In this case, "is_numeric" is precisely what is needed to verify whether the search is only a number. So the script becomes ... if (is_numeric($search)) {echo "Say something nice."; }else{ echo "Oops! You're no mathematician!";} Just a noob's 'aha moment'. ---- Server IP: 192.41.40.227 Probable Submitter: 98.203.121.127 ---- Manual Page -- http://www.php.net/manual/en/function.is-int.php Edit -- https://master.php.net/note/edit/95468 Del: integrated -- https://master.php.net/note/delete/95468/integrated Del: useless -- https://master.php.net/note/delete/95468/useless Del: bad code -- https://master.php.net/note/delete/95468/bad+code Del: spam -- https://master.php.net/note/delete/95468/spam Del: non-english -- https://master.php.net/note/delete/95468/non-english Del: in docs -- https://master.php.net/note/delete/95468/in+docs Del: other reasons-- https://master.php.net/note/delete/95468 Reject -- https://master.php.net/note/reject/95468 Search -- https://master.php.net/manage/user-notes.php
