note 24729 added to function.strcasecmp

The sample above is only true on some platforms that only use a simple 'C' locale, where individual bytes are considered as complete characters that are converted to lowercase before being differentiated. Other locales (see LC_COLLATE and LC_ALL) use the difference of collation order of characters, where characters may be groups of bytes taken from the input strings, or simply return -1, 0, or 1 as the collation order is not simply defined by comparing individual characters but by more complex rules. Don't base your code on a specific non null value returned by strcmp() or strcasecmp(): it is not portable. Just consider the sign of the result and be sure to use the correct locale! -- http://www.php.net/manual/en/function.strcasecmp.php http://master.php.net/manage/user-notes.php?action=edit+24729 http://master.php.net/manage/user-notes.php?action=delete+24729 http://master.php.net/manage/user-notes.php?action=reject+24729
