note 102088 added to function.preg-match

If someone is from a country that accepts decimal numbers in format 9.00 and 9,00 (point or comma), number validation would be like that: <?php $number_check = "9,99"; if (preg_match( '/^[\-+]?[0-9]*\.*\,?[0-9]+$/', $number_check)) { return TRUE; } ?> However, if the number will be written in the database, most probably this comma needs to be replaced with a dot. This can be done with use of str_replace, i.e : <?php $number_database = str_replace("," , "." , $number_check); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 89.201.145.12 ---- Manual Page -- http://www.php.net/manual/en/function.preg-match.php Edit -- https://master.php.net/note/edit/102088 Del: integrated -- https://master.php.net/note/delete/102088/integrated Del: useless -- https://master.php.net/note/delete/102088/useless Del: bad code -- https://master.php.net/note/delete/102088/bad+code Del: spam -- https://master.php.net/note/delete/102088/spam Del: non-english -- https://master.php.net/note/delete/102088/non-english Del: in docs -- https://master.php.net/note/delete/102088/in+docs Del: other reasons-- https://master.php.net/note/delete/102088 Reject -- https://master.php.net/note/reject/102088 Search -- https://master.php.net/manage/user-notes.php
