In PHP5:
<?php
class Foo
{
static $instances = 0;
function __construct()
{
Foo::$instances++;
}
function __destruct()
{
Foo::$instances--;
}
static function getNumInstances()
{
return Foo::$instances;
}
}
$foo = new Foo();
$fee = new Foo();
echo 'Count: '.Foo::getNumInstances()."\n";
unset( $foo );
echo 'Count: '.Foo::getNumInstances()."\n";
