What best practices should be followed when modifying PHP code with conditional statements?

When modifying PHP code with conditional statements, it is important to follow best practices to ensure readability and maintainability. One key practice is to use clear and descriptive variable names to make the logic easier to understand. Additionally, it is recommended to use proper indentation and formatting to improve code readability. Lastly, consider using comments to explain complex logic or reasoning behind the conditional statements. 

// Example of modifying PHP code with conditional statements following best practices

// Original code with unclear variable names and lack of indentation
if ($a == 1 && $b == 2){
echo "Condition met";
} else {
echo "Condition not met";
}

// Modified code with clear variable names, proper indentation, and comments
if ($user_role == 'admin' && $user_status == 'active') {
    // User is an active admin
    echo "User is an active admin";
} else {
    // User is not an active admin
    echo "User is not an active admin";
}
