note 82199 added to function.is-float

As celelibi at gmail dot com stated, is_float checks ONLY the type of the variable not the data it holds! If you want to check if string represent a floating point value use the following regular expression and not is_float(), or poorly written custom functions. /^[+-]?(([0-9]+)|([0-9]*\.[0-9]+|[0-9]+\.[0-9]*)| (([0-9]+|([0-9]*\.[0-9]+|[0-9]+\.[0-9]*))[eE][+-]?[0-9]+))$/ ---- Server IP: 217.75.128.29 Probable Submitter: 78.90.43.45 ---- Manual Page -- http://www.php.net/manual/en/function.is-float.php Edit -- https://master.php.net/note/edit/82199 Del: integrated -- https://master.php.net/note/delete/82199/integrated Del: useless -- https://master.php.net/note/delete/82199/useless Del: bad code -- https://master.php.net/note/delete/82199/bad+code Del: spam -- https://master.php.net/note/delete/82199/spam Del: non-english -- https://master.php.net/note/delete/82199/non-english Del: in docs -- https://master.php.net/note/delete/82199/in+docs Del: other reasons-- https://master.php.net/note/delete/82199 Reject -- https://master.php.net/note/reject/82199 Search -- https://master.php.net/manage/user-notes.php
