How can the issue of double counting be avoided when implementing a counter in PHP classes, as seen in the forum thread?

Issue of double counting can be avoided by implementing a static counter variable in the PHP class. By using a static variable, the counter will retain its value across multiple instances of the class and prevent double counting. 

class Counter {
    private static $count = 0;

    public function increment() {
        self::$count++;
    }

    public function getCount() {
        return self::$count;
    }
}

$counter1 = new Counter();
$counter1->increment();
$counter1->increment();

$counter2 = new Counter();
$counter2->increment();

echo $counter1->getCount(); // Output: 3
echo $counter2->getCount(); // Output: 3
