Note Submitter: yicheng zero-four at gmail dot com ---- To matsgefvert dot se and Marc, I'm sorry but I'm still having a very difficult time understanding why you would want this behavior. I understand that you are generating some code for some persistent layer for database access. In your code example, Marc, you say that you would like the SomeTable::read() to return "SomeTable" when called from your client. Yet, at this point you *know* what the class name is. Even assuming you are generating this code automatically, you can simply generate your SomeTable class as such. <?php class PersistedObject { //... public static function read($table, $key){ // do some databasey stuff // with $table which is the table name return $table; } } class SomeTable extends PersistedObject { //... // make a copy in the child class public static function read($key){ $table = get_class(); return parent::read($table, $key); } } // this will now return "SomeTable" $someTableObject = SomeTable::read(1234); ?> I'm still failing to see how this would provide but a convenience for very rare & specific issues, at the cost of non-OOP behavior by allowing static methods to bind to objects instead of classes. One of the most common uses for get_class() is for debugging lines, for example: <?php class PersistedObject { //... public static function transaction($params){ // do some stuff if ($error_occurred){ echo "Error : WTFBBQ happened in " . get_class() . "::" . __FUNCTION__ . ". Time to get some coffee!"; } } class SomeTable extends PersistedObject { //... } SomeTable::transaction( $someParams ); ?> Now, when an error occurs inside the call to SomeTable::transaction(), we get incorrect error output.
