Doc #54572 [NEW]: default ini values are not used when constructing new mysqli()

From: Operating system: MacOS PHP version: 5.3.6 Package: MySQLi related Bug Type: Documentation Problem Bug description:default ini values are not used when constructing new mysqli() Description: ------------ --- From manual page: http://www.php.net/mysqli.connect#Description --- The documentation says: mysqli::__construct() ([ string $host = ini_get("mysqli.default_host") [, string $username = ini_get("mysqli.default_user") [, string $passwd = ini_get("mysqli.default_pw") [, string $dbname = "" [, int $port = ini_get("mysqli.default_port") [, string $socket = ini_get("mysqli.default_socket") ]]]]]] ) this implies that you can set these values via ini_set() and instantiate a new mysqli() with no arguments, but this does not actually work. This is similar to http://bugs.php.net/bug.php?id=38998&edit=2 except that case revolved around passing null to the constructor. The documentation says: "If not provided or NULL, the MySQL server will attempt to authenticate the user against those user records which have no password only. This allows one username to be used with different permissions (depending on if a password as provided or not)." but this is inconsistent with the constructor signature which implies that these values are auto-populated from the ini values. If the ini parameters serve no purpose in an empty constructor invocation, then the documentation signature should be updated to reflect that the mysql.default_* ini values have no effect (or are overridden by the behavior that follows). i.e. the signature should read mysqli::__construct() ([ string $host = "localhost" [, string $username = ini_get("mysqli.default_user") [, string $passwd = "" [, string $dbname = "" [, int $port = ini_get("mysqli.default_port") [, string $socket = ini_get("mysqli.default_socket") ]]]]]] ) which implies a very different behavior. Test script: --------------- ini_set("mysqli.default_host", "localhost"); ini_set("mysqli.default_user", "jack"); ini_set("mysqli.default_pw", "florey"); $sadmysqli = new mysqli(); $happymysqli = new mysqli(ini_get("mysqli.default_host"), ini_get("mysqli.default_user"), ini_get("mysqli.default_pw")); print_r($sadmysqli->host_info); // ERROR: DB::__construct() [<a href='db.--construct'>db.--construct</a>]: Property access is not allowed yet print_r($happymysqli->host_info); // Localhost via UNIX socket Expected result: ---------------- the result for both print_r statements should be equivalent. this makes it seem as if the default ini values for the constructor are not actually being used when calling the constructor Actual result: -------------- see above, namely DB::__construct() [<a href='db.--construct'>db.--construct</a>]: Property access is not allowed yet -- Edit bug report at http://bugs.php.net/bug.php?id=54572&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=54572&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=54572&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=54572&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=54572&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=54572&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=54572&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=54572&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=54572&r=needscript Try newer version: http://bugs.php.net/fix.php?id=54572&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=54572&r=support Expected behavior: http://bugs.php.net/fix.php?id=54572&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=54572&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=54572&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=54572&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=54572&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=54572&r=dst IIS Stability: http://bugs.php.net/fix.php?id=54572&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=54572&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=54572&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=54572&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=54572&r=mysqlcfg
