Are there any potential drawbacks to storing object names in an array instead of the objects themselves in PHP?

Storing object names in an array instead of the objects themselves in PHP can lead to potential issues such as increased memory usage and decreased performance, as each object name will need to be resolved to its corresponding object. To solve this issue, it is recommended to store the objects themselves in the array rather than just their names.

// Storing objects in an array
$objects = [
    new MyClass(),
    new AnotherClass(),
    new YetAnotherClass()
];

// Accessing objects from the array
foreach ($objects as $object) {
    // Do something with $object
}
