How can PHP developers effectively manage and manipulate time values to achieve the desired results without compromising accuracy or efficiency?

PHP developers can effectively manage and manipulate time values by utilizing PHP's built-in date and time functions, such as strtotime(), date(), and DateTime. It is important to properly handle time zones and format conversions to ensure accuracy. Additionally, using the DateTime class can simplify date and time calculations while maintaining efficiency.

// Example: Convert a date string to a different format
$dateString = '2022-01-15';
$dateTime = new DateTime($dateString);
$formattedDate = $dateTime->format('Y-m-d');

echo $formattedDate;
