How can the combination of strftime and strtotime functions in PHP be helpful in date manipulation tasks?
When working with dates in PHP, the combination of the `strftime` and `strtotime` functions can be helpful in manipulating dates. `strftime` is used to format a timestamp into a string representation of a date, while `strtotime` is used to parse any English textual datetime description into a Unix timestamp. By using these functions together, you can easily convert, format, and manipulate dates in PHP.
$date = strtotime('2022-01-01'); // Convert a date string to a Unix timestamp
$formatted_date = strftime('%B %d, %Y', $date); // Format the Unix timestamp into a readable date string
echo $formatted_date; // Output: January 01, 2022
