#26470 [NEW]: setlocale(): Difference between 0 and NULL locale

From: mail at ulrich-voelkel dot de Operating system: Gentoo Linux PHP version: 4.3.3 PHP Bug Type: Documentation problem Bug description: setlocale(): Difference between 0 and NULL locale Description: ------------ Hi there! On http://de.php.net/manual/en/function.setlocale.php the description of "string setlocale ( mixed category, array locale)" says "If locale is NULL or "0", the locale setting is not affected, only the current setting is returned." On my Gentoo Box I figured out that giving "NULL" behaves different to "0". After setting the LC_ALL from the C locale to "de_DE" (or anything else) "setlocale(LC_ALL, 0)" worked correctly and returnd all locale Variables with their values set to "de_DE" (as expected). Refering to the Documentation I expected the same result from "setlocale(LC_ALL, NULL) but I didn`t get it. It just set all locale vaiables back to the default C Value. Thanks for your efforts, Uli Reproduce code: --------------- <?php echo "Default locale: " . setlocale(LC_ALL, 0) . "<br />"; setlocale(LC_ALL, "de_DE"); $locales = explode(";", setlocale(LC_ALL, NULL)); echo "New locale: "; print_r($locales); ?> Expected result: ---------------- Default locale: C New locale: Array ( [0] => LC_CTYPE=de_DE [1] => LC_NUMERIC=C [2] => LC_TIME=de_DE [3] => LC_COLLATE=de_DE [4] => LC_MONETARY=de_DE [5] => LC_MESSAGES=de_DE [6] => LC_PAPER=de_DE [7] => LC_NAME=de_DE [8] => LC_ADDRESS=de_DE [9] => LC_TELEPHONE=de_DE [10] => LC_MEASUREMENT=de_DE [11] => LC_IDENTIFICATION=de_DE ) Actual result: -------------- Default locale: C New locale: Array ( [0] => C ) -- Edit bug report at http://bugs.php.net/?id=26470&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=26470&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=26470&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=26470&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=26470&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=26470&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=26470&r=needscript Try newer version: http://bugs.php.net/fix.php?id=26470&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=26470&r=support Expected behavior: http://bugs.php.net/fix.php?id=26470&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=26470&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=26470&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=26470&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=26470&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=26470&r=dst IIS Stability: http://bugs.php.net/fix.php?id=26470&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=26470&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=26470&r=float
