/**

* emulation of destructors.
|
|
*
|
|
* If you want a destructor in your class, inherit PEAR 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 PEAR constructor: <code>$this->PEAR();</code>.
|
|
* 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 <code>error_log()</code>, <code>syslog()</code> or
|
|
* something like that instead.
