How does the inclusion of a Trait through a "use" statement in PHP affect the memory usage of objects?

When a Trait is included in a class using the "use" statement in PHP, it does not affect the memory usage of objects directly. Traits are essentially code snippets that are copied into the class during compilation, so they do not add any additional memory overhead at runtime. However, if the Trait contains a lot of code or heavy operations, it can indirectly affect memory usage by increasing the size of the class. 

<?php

trait MyTrait {
    // Trait code here
}

class MyClass {
    use MyTrait;
    // Class code here
}

// Usage
$obj = new MyClass();
