note 74013 added to function.is-numeric

In reply to www.kigoobe.com, a more strict expression is <?php function my_is_numeric($value) { return (preg_match ("/^(-){0,1}([0-9]+)(,[0-9][0-9][0-9])*([.][0-9]){0,1}([0-9]*)$/", $value) == 1); } ?> This will not match strings like -6,77.8,8 which are matched by the below expression, and instead requires a single decimal point, with at least one character following, and only permits comma-separation when the right hand side is a triplet. ---- Server IP: 194.145.210.3 Probable Submitter: 86.129.76.181 ---- Manual Page -- http://www.php.net/manual/en/function.is-numeric.php Edit -- https://master.php.net/note/edit/74013 Del: integrated -- https://master.php.net/note/delete/74013/integrated Del: useless -- https://master.php.net/note/delete/74013/useless Del: bad code -- https://master.php.net/note/delete/74013/bad+code Del: spam -- https://master.php.net/note/delete/74013/spam Del: non-english -- https://master.php.net/note/delete/74013/non-english Del: in docs -- https://master.php.net/note/delete/74013/in+docs Del: other reasons-- https://master.php.net/note/delete/74013 Reject -- https://master.php.net/note/reject/74013 Search -- https://master.php.net/manage/user-notes.php
