How can PHP be instructed to recognize a string as a timestamp and use date_format to convert the timestamp?

To instruct PHP to recognize a string as a timestamp and use date_format to convert it, you can use the strtotime function to convert the string into a Unix timestamp. Once you have the timestamp, you can use the date function along with the date_format parameter to format the timestamp into the desired date format.

// Example string representing a timestamp
$timestampString = "2022-01-15 10:30:00";

// Convert the string to a Unix timestamp
$timestamp = strtotime($timestampString);

// Format the timestamp into a desired date format
$formattedDate = date_format(date_create($timestamp), 'Y-m-d H:i:s');

echo $formattedDate;
