How can PHP beginners efficiently convert hours and minutes into a format that allows for accurate time calculations?

When converting hours and minutes into a format that allows for accurate time calculations in PHP, beginners can use the PHP DateTime class to easily handle time calculations. By creating a new DateTime object and setting the hours and minutes accordingly, beginners can perform accurate time calculations such as addition, subtraction, and formatting.

$time->setTime($hours, $minutes);

echo $time->format('H:i'); // Output: 03:30
