How can PHP functions be used to extract and format specific parts of a datetime value for display?
When working with datetime values in PHP, you can use built-in functions like date() to extract and format specific parts of the datetime value for display. For example, if you have a datetime value stored in a variable $datetime, you can use date('Y-m-d', strtotime($datetime)) to extract and format just the date part. Similarly, you can use date('H:i:s', strtotime($datetime)) to extract and format just the time part.
// Assuming $datetime contains the datetime value
$date = date('Y-m-d', strtotime($datetime));
$time = date('H:i:s', strtotime($datetime));
echo "Date: " . $date . "<br>";
echo "Time: " . $time;
