Hi,
I’ve reviewed my uses of mysqli->close() in the wrapper class around mysqli I
wrote several years ago. All of them were useless, and I have just deleted them
after having carefully checked the documentation. Here is the most obvious case
(yes, this is real code):
```php
public function __destruct() {
if ($this->link !== null) {
@ $this->link->close();
$this->link = null;
}
}
```
I wished that mysqli->close() were never implemented...
Methods like mysqli->close() are innocuous by themselves. The issue is that
users are tempted, even incited, to do manual operations that are very well
done automatically (in this case, by the garbage collector). They are also
driven to ask themselves questions that they don’t need to bother (“what if
disconnection fails?”).
If you still have good reasons to add such a method in pdo. I recommend to use
a name that deters users from using it in normal operations, e.g.
pdo->debug_manual_disconnect().
