How can object properties be preserved and accessed efficiently when linking to PHP files using "a href" tags?
When linking to PHP files using "a href" tags, object properties can be preserved and accessed efficiently by passing them as URL parameters. This can be done by appending the object properties to the URL in the href attribute of the anchor tag. In the PHP file that is being linked to, these parameters can be accessed using the $_GET superglobal array.
<a href="example.php?property1=value1&property2=value2">Link</a>
```
In example.php:
```php
<?php
$property1 = $_GET['property1'];
$property2 = $_GET['property2'];
// Use $property1 and $property2 as needed
?>
