-/**
- * Base class for other PEARgw classes. Provides rudimentary
- * emulation of destructors.
- *
- * If you want a destructor in your class, inherit PEARgw and make a
- * destructor method called _yourclassname (same name as the
- * constructor, but with a "_" prefix). Also, in your constructor you
- * have to call the PEARgw constructor: $this->PEARgw();.
- * The destructor method will be called without parameters. Note that
- * at in some SAPI implementations (such as Apache), any output during
- * the request shutdown (in which destructors are called) seems to be
- * discarded. If you need to get any debug information from your
- * destructor, use error_log(), syslog() or something similar.
- *
- * IMPORTANT! To use the emulated destructors you need to create the
- * objects by reference: $obj =& new PEARgw_child;
- *
- * @since PHP 4.0.2
