In PHP, to map objects in a memory-efficient way, you can use PHP's built-in functions and data structures effectively. Below is an example that demonstrates how to achieve this through the use of arrays and leveraging references to reduce memory usage.
<?php
// Example of mapping objects in a memory-efficient way
class User {
public $name;
public $email;
public function __construct($name, $email) {
$this->name = $name;
$this->email = $email;
}
}
// Creating an array of user objects
$users = [];
$users[] = new User('John Doe', 'john@example.com');
$users[] = new User('Jane Smith', 'jane@example.com');
// Mapping user names to email addresses
$userMap = [];
foreach ($users as $user) {
// Using references to save memory
$userMap[$user->name] =& $user->email;
}
// Output the user map
print_r($userMap);
?>
