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