How can PHP scripts be modified to correctly display timestamps in a human-readable format instead of the Unix epoch time?
When displaying timestamps in a human-readable format in PHP, you can use the `date()` function to convert Unix epoch time to a readable format. Simply pass the Unix timestamp as the second argument to the `date()` function along with the desired format specifier.
$timestamp = 1626840000; // Unix epoch time
$human_readable_time = date('Y-m-d H:i:s', $timestamp);
echo $human_readable_time;
