* If ICloseable is implemented __destruct() should also be added to the class and should call close in it:
|
|
*
|
|
* <code>
|
|
* public function close(): void {
|
|
* fclose($this->resource);
|
|
* }
|
|
*
|
|
* public function __destruct() {
|
|
* $this->close();
|
|
* }
|
|
* </code>
|
|
*
|
|
* However if close() is only implemented because a parent interface requires it, the __destruct() implementation may be omitted.
