What best practices can be followed to simplify and optimize PHP code for better readability and maintenance?

To simplify and optimize PHP code for better readability and maintenance, it is recommended to follow best practices such as using meaningful variable names, breaking down complex logic into smaller functions, utilizing comments to explain the code, and adhering to coding standards like PSR-12. 

// Example of implementing best practices for better readability and maintenance

// Use meaningful variable names
$firstName = 'John';
$lastName = 'Doe';

// Break down complex logic into smaller functions
function getFullName($firstName, $lastName) {
    return $firstName . ' ' . $lastName;
}

// Utilize comments to explain the code
// Get the full name of the user
$fullName = getFullName($firstName, $lastName);

// Adhere to coding standards like PSR-12
class ExampleClass
{
    public function exampleMethod()
    {
        // Method implementation
    }
}
