note 79634 added to function.is-float

Your function thinks my address is a floating point number. So it's not perfect. Really what I want is a function that allows ctype_digit() to fail once, but only once, when it hits a period. function better_float_check($float) { $periods=0; $split = split('', $float); foreach ($split as $s) { if (!ctype_digit($s)) { if ($s!='.') return false; else $periods++; } } if ($periods==1) return true; // all digits and only 1 decimal else return false; // more than one decimal } ---- Server IP: 208.69.120.35 Probable Submitter: 71.116.64.139 ---- Manual Page -- http://www.php.net/manual/en/function.is-float.php Edit -- https://master.php.net/note/edit/79634 Del: integrated -- https://master.php.net/note/delete/79634/integrated Del: useless -- https://master.php.net/note/delete/79634/useless Del: bad code -- https://master.php.net/note/delete/79634/bad+code Del: spam -- https://master.php.net/note/delete/79634/spam Del: non-english -- https://master.php.net/note/delete/79634/non-english Del: in docs -- https://master.php.net/note/delete/79634/in+docs Del: other reasons-- https://master.php.net/note/delete/79634 Reject -- https://master.php.net/note/reject/79634 Search -- https://master.php.net/manage/user-notes.php
