What are the advantages and disadvantages of using gmdate() versus Now() for date manipulation in PHP?

When working with dates in PHP, the gmdate() function is useful for obtaining the current GMT/UTC time, while the Now() function provides the current date and time based on the server's timezone settings. The advantage of using gmdate() is that it always returns the GMT/UTC time, which can be helpful for consistency in date calculations across different timezones. However, the disadvantage is that it may not reflect the actual local time if you need to display it to users in their timezone. On the other hand, Now() will give you the local time, but it may require additional timezone conversions for consistency in date calculations. 

// Using gmdate() for GMT/UTC time
$gmt_time = gmdate('Y-m-d H:i:s');

// Using Now() for local time
$local_time = date('Y-m-d H:i:s');
