Php constructor and Destructor analysis

Class counter { Private static $ count = 0; Function _ construct () { Self: $ count ++; } Function _ destruct () { Self: $ count --; } Function getcount () { Return self: $ count; } } // Create the first instance $ C = new counter (); // Output 1 Print ($ c-> getcount ()." \ N "); // Create the second instance $ C2 = new counter (); // Output 2 Print ($ c-> getcount ()." \ N "); // Destroy the instance $ C2 = null; // Output 1 Print ($ c-> getcount ()." \ N "); ?> Note: When a new instance is created, the memory is prepared to store all the attributes. each instance has its own unique set of attributes. However, the method is shared by all instances of this class.
