Regarding Example #1: Be sure to "sanitize" your variables before using them for including files. Example #1 assumes the variable $type contains sanitized data (and NOT something threatening like '../../../../../etc/passwd'). One approach might be as follows: <?php switch ( $type ) { case "MySQL": $type = 'mysql'; break; case "SQLite": $type = 'sqlite'; break; default: throw new Exception ('Driver not found'); } if (include_once 'Drivers/' . $type . '.php') { $classname = 'Driver_' . $type; return new $classname; } else { throw new Exception ('Driver not found'); } ?> Naturally, the examples are brief and intended to express the issue at hand, not input sanitizing methods, but someone might find this note helpful.
