note 82857 added to function.is-int

I've found that both that is_int and ctype_digit don't behave quite as I'd expect, so I made a simple function called isInteger which does. I hope somebody finds it useful. <?php function isInteger($input){ return(ctype_digit(strval($input))); } var_dump(is_int(23)); //bool(true) var_dump(is_int("23")); //bool(false) var_dump(is_int(23.5)); //bool(false) var_dump(is_int(NULL)); //bool(false) var_dump(is_int("")); //bool(false) var_dump(ctype_digit(23)); //bool(true) var_dump(ctype_digit("23")); //bool(false) var_dump(ctype_digit(23.5)); //bool(false) var_dump(ctype_digit(NULL)); //bool(false) var_dump(ctype_digit("")); //bool(true) var_dump(isInteger(23)); //bool(true) var_dump(isInteger("23")); //bool(true) var_dump(isInteger(23.5)); //bool(false) var_dump(isInteger(NULL)); //bool(false) var_dump(isInteger("")); //bool(false) ?> ---- Server IP: 92.48.100.16 Probable Submitter: 82.71.8.209 ---- Manual Page -- http://www.php.net/manual/en/function.is-int.php Edit -- https://master.php.net/note/edit/82857 Del: integrated -- https://master.php.net/note/delete/82857/integrated Del: useless -- https://master.php.net/note/delete/82857/useless Del: bad code -- https://master.php.net/note/delete/82857/bad+code Del: spam -- https://master.php.net/note/delete/82857/spam Del: non-english -- https://master.php.net/note/delete/82857/non-english Del: in docs -- https://master.php.net/note/delete/82857/in+docs Del: other reasons-- https://master.php.net/note/delete/82857 Reject -- https://master.php.net/note/reject/82857 Search -- https://master.php.net/manage/user-notes.php
