How can PHP developers effectively utilize debugging strategies like the Strategy Pattern and Dependency Injection for efficient debugging processes?

When debugging PHP code, developers can effectively utilize the Strategy Pattern by creating different debugging strategies (e.g., logging, error handling) that can be easily switched based on the current debugging needs. Dependency Injection can help by allowing developers to inject dependencies (e.g., logging classes, error handling classes) into their code, making it easier to test and debug different components independently. 

// Implementing the Strategy Pattern for debugging

interface DebuggingStrategy {
    public function debug($message);
}

class LoggingStrategy implements DebuggingStrategy {
    public function debug($message) {
        // Implement logging logic here
    }
}

class ErrorHandlingStrategy implements DebuggingStrategy {
    public function debug($message) {
        // Implement error handling logic here
    }
}

class DebuggingContext {
    private $strategy;

    public function setStrategy(DebuggingStrategy $strategy) {
        $this->strategy = $strategy;
    }

    public function debug($message) {
        $this->strategy->debug($message);
    }
}

// Implementing Dependency Injection for debugging

class MyClass {
    private $logger;

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

    public function myMethod() {
        // Debugging logic
        $this->logger->debug('Debug message');
    }
}

// Usage
$logger = new LoggingStrategy();
$context = new DebuggingContext();
$context->setStrategy($logger);

$myClass = new MyClass($context);
$myClass->myMethod();
