note 125563 added to filter.filters.sanitize

Although it's specifically mentioned in the above documentation, because many seem to find this unintuitive it's worth pointing out that FILTER_SANITIZE_NUMBER_FLOAT will remove the decimal character unless you specify FILTER_FLAG_ALLOW_FRACTION: <?php $number_string = '12.34'; echo filter_var( $number_string, FILTER_SANITIZE_NUMBER_FLOAT ); // 1234 echo filter_var( $number_string, FILTER_SANITIZE_NUMBER_FLOAT, FILTER_FLAG_ALLOW_FRACTION ); // 12.34 ?> ---- Server IP: 45.112.84.4 Probable Submitter: 45.91.156.130 (proxied: 2a01:cb1d:8017:f300:62a4:4cff:fe02:4b57) ---- Manual Page -- http://php.net/manual/en/filter.filters.sanitize.php Edit -- https://master.php.net/note/edit/125563 Del: integrated -- https://master.php.net/note/delete/125563/integrated Del: useless -- https://master.php.net/note/delete/125563/useless Del: bad code -- https://master.php.net/note/delete/125563/bad+code Del: spam -- https://master.php.net/note/delete/125563/spam Del: non-english -- https://master.php.net/note/delete/125563/non-english Del: in docs -- https://master.php.net/note/delete/125563/in+docs Del: other reasons-- https://master.php.net/note/delete/125563 Reject -- https://master.php.net/note/reject/125563 Search -- https://master.php.net/manage/user-notes.php
