Note Submitter: anthony dot scaife at firedupgroup dot co dot uk ---- I don't understand the issues you all seem to be having with class constants. For me they are simply another method of grouping related functions and data together in a logical package, and keeping things out of global scope. Class constants were something I felt very much missing from PHP4 (I have a background in C++). You can use them like this <?php class mySql { const ERR_CONN = 'Connection attempt failed'; const ERR_SELECT_DB = 'Database selection attempt failed'; const ERR_QUERY = 'Invalid SQL query'; // .... etc } ?> Later, you could then use the constants like this <?php $err = $db->getErr(); echo "<!-- DB failure : $err -->"; switch($err) { case mySql::ERR_CONN: // Do this case mySql::ERR_SELECT_DB: // Do that case mySql::ERR_QUERY: // Do something else } ?> and if you need to find what other constants the class uses, you just find the class !
