note 76841 added to function.number-format

Beware of this pitfall: $value = number_format ($float_val, 2, "."); This will silently return an empty string and not throw an error, at least with PHP 5.x. This is the corrected code: $value = number_format ($float_val, 2, ".", ","); - or - $value = number_format ($float_val, 2); You must specifiy either the decimal point AND thousands separator else neither, otherwise you'll run into this issue. I just spent over 30min debugging code with this problem! ---- Server IP: 208.69.120.35 Probable Submitter: 166.129.83.175 ---- Manual Page -- http://www.php.net/manual/en/function.number-format.php Edit -- https://master.php.net/note/edit/76841 Del: integrated -- https://master.php.net/note/delete/76841/integrated Del: useless -- https://master.php.net/note/delete/76841/useless Del: bad code -- https://master.php.net/note/delete/76841/bad+code Del: spam -- https://master.php.net/note/delete/76841/spam Del: non-english -- https://master.php.net/note/delete/76841/non-english Del: in docs -- https://master.php.net/note/delete/76841/in+docs Del: other reasons-- https://master.php.net/note/delete/76841 Reject -- https://master.php.net/note/reject/76841 Search -- https://master.php.net/manage/user-notes.php
