What is the best practice for handling errors in PHP classes and transferring them to other classes?

When handling errors in PHP classes and transferring them to other classes, it is best practice to use exceptions to handle errors and pass them up the call stack. This allows for better error handling and logging, as well as separating error handling from normal program flow. 

class MyClass {
    public function doSomething() {
        try {
            // Code that may throw an exception
        } catch (Exception $e) {
            throw new Exception("An error occurred in MyClass: " . $e->getMessage());
        }
    }
}

class AnotherClass {
    public function doSomethingElse() {
        $myClass = new MyClass();
        
        try {
            $myClass->doSomething();
        } catch (Exception $e) {
            throw new Exception("An error occurred in AnotherClass: " . $e->getMessage());
        }
    }
}

$anotherClass = new AnotherClass();

try {
    $anotherClass->doSomethingElse();
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}
