Bug #76435 [Opn]: Float with decimals Filter issue with Ca_fr locale

Edit report at https://bugs.php.net/bug.php?id=76435&edit=1 ID: 76435 Updated by: cmb@php.net Reported by: joel dot lamothe dot 42 at gmail dot com Summary: Float with decimals Filter issue with Ca_fr locale Status: Open Type: Bug Package: Filter related Operating System: Windows PHP Version: 7.1.18 Block user comment: N Private report: N New Comment: Not only is FILTER_SANITIZE_NUMBER_FLOAT not locale aware, but there also is no possibility to manually override the decimal and thousand separators[1] (like for FILTER_VALIDATE_FLOAT), which rather limits its usefulness. In this case one can get around this limitation by using the flag FILTER_FLAG_ALLOW_THOUSAND instead of FILTER_FLAG_ALLOW_FRACTION[2], but that's quite a hack.

Test script: --------------- <?php setlocale(LC_ALL, 'fr_CA.utf-8'); $number = 25 / 2; $temp = filter_var($number, FILTER_SANITIZE_NUMBER_FLOAT, FILTER_FLAG_ALLOW_FRACTION); echo $temp; ?> Expected result: ---------------- 12,5 Actual result: -------------- 125 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76435&edit=1
