From: alef0 at freenet dot de Operating system: gentoo PHP version: 5.2CVS-2009-05-18 (CVS) PHP Bug Type: Math related Bug description: Type conversion into a float respects the numeric settings of the locale Description: ------------ PHP version: 5.2.6RC4-pl0-gentoo Conversion using floatval() or (float) respects the numeric settings of the locale. THIS IS VERY DANGEROUS CAUSE YOU WILL GET WRONG RESULTS BY APPLYING ANY MATH METHODE ON CONVERTED FLOATS! Reproduce code: --------------- $var = '122.34343The'; //expected float: 122.34343 setlocale(LC_NUMERIC, 'en_US.utf8'); $float_value_of_var = (float) $var; print 'Locale dec sep point: (float) ' . $var . ' = ' . $float_value_of_var; $float_value_of_var = floatval($var); print ' or floatval(' . $var . ') = ' . $float_value_of_var . "<br /><br />\n\n"; setlocale(LC_NUMERIC, 'de_DE.utf8'); $float_value_of_var = (float) $var; print 'Locale dec sep comma: (float) ' . $var . ' = ' . $float_value_of_var; $float_value_of_var = floatval($var); print ' or floatval(' . $var . ') = ' . $float_value_of_var . "<br /><br />\n\n"; Expected result: ---------------- Locale dec sep point: (float) 122.34343The = 122.34343 or floatval(122.34343The) = 122.34343 Locale dec sep comma: (float) 122.34343The = 122.34343 or floatval(122.34343The) = 122.34343 Actual result: -------------- Locale dec sep point: (float) 122.34343The = 122.34343 or floatval(122.34343The) = 122.34343 Locale dec sep comma: (float) 122.34343The = 122,34343 or floatval(122.34343The) = 122,34343 -- Edit bug report at http://bugs.php.net/?id=48315&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48315&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48315&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48315&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48315&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48315&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48315&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48315&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48315&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48315&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48315&r=support Expected behavior: http://bugs.php.net/fix.php?id=48315&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48315&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48315&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48315&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48315&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48315&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48315&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48315&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48315&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48315&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48315&r=mysqlcfg
