ID: 30619 Updated by: [EMAIL PROTECTED] Reported By: junk at pneyman dot com Status: Bogus Bug Type: Scripting Engine problem Operating System: Fedora Core 2, kernel 2.6.5 PHP Version: 5.0.2 New Comment:
The line private static $currentDb = PostgresDb; should read private static $currentDb = self::PostgresDb; Example: $ cat test.php <?php class Foo { const PostgresDb = 'PostgreSQL'; private static $dbname= self::PostgresDb; public static function test() { var_dump(self::PostgresDb, self::$dbname); } } Foo::test(); ?> $ php5 test.php string(10) "PostgreSQL" string(10) "PostgreSQL" Previous Comments: ------------------------------------------------------------------------ [2004-11-04 10:36:29] [EMAIL PROTECTED] Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. change .. private static $currentDb = PostgresDb; ... to .. private static $currentDb = 'PostgresDb'; ... ------------------------------------------------------------------------ [2004-10-30 07:00:33] junk at pneyman dot com Description: ------------ Seems that there's no way to address the class constant from within a static method declared in the same class. Script is parsed by the engine, but I get a warning notice: Use of undefined constant 'xxx', assuming 'xxx'. The name of the constant assumed is identical to the one I want to address. The substitution then occurs correctly, and script works. However, I couldn't find a way to call cosntant correctly to avoid warning message and guesswork from the engine. self:: resolution operator doesn't help either. Reproduce code: --------------- include_once("db/PostGreSqlDbProfile.php"); include_once("db/MySqlDbProfile.php"); class InitStingray { // constants const PostgresDb = 'PostGreSQL'; const MysqlDb = 'MySQL'; // private variables private static $currentDb = PostgresDb; private static $db = NULL; // public methods private static function initDb () { // xxx: problem addressing constant PostgresDb if (self::$currentDb == self::PostgresDb) { self::$db = new PostGreSqlDbProfile(); } // xxx: problem addressing constant MySqlDb else if (self::$currentDb = self::MysqlDb) { self::$db = new MySqlDbProfile(); } } public static function getDb () { if (self::$db == NULL) { self::initDb(); return self::$db; } else { return self::$db; } } } Expected result: ---------------- Substitution of the name of the constant for its value should occur, and comparisons between variable $currentDb and predefined values "Postgres" and "Mysql" should take place. No warnings should be issued. Actual result: -------------- Warning is issued that the script cannot locate the constant I'm addressing, however guesses that I'm trying to call a cosntant with the same name and correctly does the substitution issuing a warning notice. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=30619&edit=1
