Note Submitter: james.holwell( at )exeter.ox.ac.uk ---- 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.
