The function filter_var($x, FILTER_SANITIZE_NUMBER_FLOAT) should not return a float instead string? Kind regards, Cyb10101 Test script: --------------- <?php function d($a = '', $x, $z = ' | ') {echo $a; var_dump($x); echo $z;} function run($x) { d('init=', $x); d('bool=', (filter_var($x, FILTER_VALIDATE_FLOAT) ? 'Valid' : 'Not Valid')); d('validate=', filter_var($x, FILTER_VALIDATE_FLOAT)); d('sanitize=', filter_var($x, FILTER_SANITIZE_NUMBER_FLOAT), "<br />\n"); } run(0.5); // init=float(0.5) | bool=string(5) "Valid" | validate=float(0.5) | sanitize=string(2) "05" run('0.5'); // init=string(3) "0.5" | bool=string(5) "Valid" | validate=float(0.5) | sanitize=string(2) "05" Expected result: ---------------- run(0.5); // ... | sanitize=float(0.5) run('0.5'); // ... | sanitize=float(0.5) -- Edit bug report at https://bugs.php.net/bug.php?id=71319&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71319&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71319&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71319&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71319&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71319&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71319&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71319&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71319&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71319&r=support Expected behavior: https://bugs.php.net/fix.php?id=71319&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71319&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71319&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71319&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71319&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71319&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71319&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71319&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71319&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71319&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71319&r=mysqlcfg
