How can a UNIX timestamp be converted into a normal time format in PHP?

To convert a UNIX timestamp into a normal time format in PHP, you can use the `date()` function along with the timestamp value. The `date()` function formats a local time/date based on the format specified. You can pass the timestamp as the second argument to get the desired time format.

$timestamp = 1609459200; // Example UNIX timestamp
$normal_time = date('Y-m-d H:i:s', $timestamp);
echo $normal_time;
