#26470 [Opn->Csd]: setlocale(): Difference between 0 and NULL locale

ID: 26470 Updated by: vrana@php.net Reported By: mail at ulrich-voelkel dot de -Status: Open +Status: Closed Bug Type: Documentation problem Operating System: Gentoo Linux PHP Version: 4.3.3 New Comment: This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. Null is equivalent to '', not '0'.

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 this bug report at http://bugs.php.net/?id=26470&edit=1
