PHP Destructor

This lesson is part of PHP · All levels

Summary

Destructor is a __destruct method that PHP runs when an object is no longer in use or when the script is finished. Destructor is useful for clearing resources such as closing files, connections, or database cursors. If the class does not define the destructor, PHP simply releases the object memory without additional action.

Key points

Destructor is written as __destruct and runs automatically when the object is destroyed.
Destructor is useful for clearing open resources in the constructor.
The destructor execution sequence follows the time the object is released, not the manufacturing sequence.
A class can only have one destructor.
