How can PHP developers ensure that their code is easily understandable and helpful to others who may come across their forum threads seeking solutions?

To ensure that PHP code is easily understandable and helpful to others, PHP developers can follow these guidelines: 1. Use clear and descriptive variable names. 2. Comment the code to explain the purpose of each section. 3. Break down complex tasks into smaller, more manageable functions. 4. Follow best practices and coding standards to maintain consistency. Example: Issue: How to validate an email address in PHP? Code snippet: 

$email = "test@example.com";

if(filter_var($email, FILTER_VALIDATE_EMAIL)) {
    echo "Valid email address";
} else {
    echo "Invalid email address";
}
