How can PHP developers ensure efficient memory usage when working with a large number of objects in a loop?

When working with a large number of objects in a loop in PHP, developers can ensure efficient memory usage by properly managing object references and memory allocation. One way to achieve this is by unsetting object references after they are no longer needed within the loop. This helps free up memory and prevent memory leaks.

// Example of efficiently managing memory usage in a loop with objects
$objects = []; // Array to store objects

for ($i = 0; $i < 1000; $i++) {
    $object = new stdClass(); // Create a new object
    // Do something with the object
    
    // Add the object to the array
    $objects[] = $object;
    
    // Unset the object reference to free up memory
    unset($object);
}

// Continue working with the objects in the $objects array
foreach ($objects as $obj) {
    // Do something with each object
}
