In what scenarios is it more appropriate to check dependencies only when working with specific properties in PHP classes?

When working with specific properties in PHP classes, it is more appropriate to check dependencies only when those properties are being accessed or modified. This approach helps improve performance by avoiding unnecessary checks when the dependencies are not needed. By checking dependencies only when necessary, you can ensure that your code is more efficient and focused on the specific task at hand. 

class MyClass {
    private $dependency;

    public function __construct($dependency) {
        $this->dependency = $dependency;
    }

    public function setDependency($dependency) {
        $this->dependency = $dependency;
    }

    public function getProperty() {
        if ($this->dependency) {
            // do something with the dependency
        }
    }
}
