What are the differences between gmdate() and date() functions in PHP, and when should each be used?

The main difference between gmdate() and date() functions in PHP is that gmdate() returns the current date and time in Greenwich Mean Time (GMT) timezone, while date() returns the current date and time based on the server's timezone settings. Use gmdate() when you specifically need to work with GMT timezone, such as when dealing with international time comparisons or when you want to ensure consistency across different timezones. Use date() when you need to work with the server's timezone or when you want to display the date and time based on the user's local timezone. 

// Using gmdate() to get the current date and time in GMT timezone
$gmt_date = gmdate('Y-m-d H:i:s');

// Using date() to get the current date and time based on server's timezone
$server_date = date('Y-m-d H:i:s');
