first we have to create a class with parameters or with out parameters and with some funtions.
like class Test{
$no;
$name;
function Exampleclass(){
$no=0;
$name=NULL;
}
function setNo($num)
{
$no=$num;
}
function setName($uname)
{
$name=$uname;
}
function getNo(){
return $this->no;
}
function getName(){
return $this->name;
}
}
class TestExample{
$testexample= new Exampleclass();
$testexample->setNo(1);
$testexample->setName(’aa’);
$testexample->getNo();
$testexample->getName();
}

The Object $testexample is still live untill the script is running or if you forcefully destroy with using the unset() function. If you use the constructor & deconstructor than it is automation the destroy at the end of the script.

One More think if you have two deconstructor for parient & child class than only the child’s class deconstructor is execute automatic. for calling the parent you must call them like.. parent::__deconstructor();
