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