note 86796 added to function.is-numeric

Using SpT_King James example, i've re-wrote to cater for digits starting with '+', commas ',' or period '.' function is_numeric_regex($str) { $str = "{$str}"; if (in_array($str[0], array('-', '+'))) $str = "{$str[0]}0" . substr($str, 1); else $str = "0{$str}"; $eng = preg_match ("/^[+,-]{0,1}([0-9]+)(,[0-9][0-9][0-9])*([.][0-9]){0,1}([0-9]*)$/" , $str) == 1; $world = preg_match ("/^[+,-]{0,1}([0-9]+)(.[0-9][0-9][0-9])*([,][0-9]){0,1}([0-9]*)$/" , $str) == 1; return ($eng or $world); } ---- Server IP: 69.147.83.197 Probable Submitter: 196.27.71.225 ---- Manual Page -- http://www.php.net/manual/en/function.is-numeric.php Edit -- https://master.php.net/note/edit/86796 Del: integrated -- https://master.php.net/note/delete/86796/integrated Del: useless -- https://master.php.net/note/delete/86796/useless Del: bad code -- https://master.php.net/note/delete/86796/bad+code Del: spam -- https://master.php.net/note/delete/86796/spam Del: non-english -- https://master.php.net/note/delete/86796/non-english Del: in docs -- https://master.php.net/note/delete/86796/in+docs Del: other reasons-- https://master.php.net/note/delete/86796 Reject -- https://master.php.net/note/reject/86796 Search -- https://master.php.net/manage/user-notes.php
