What is the ISO 8601 date format and how can it be converted to a different format in PHP?

The ISO 8601 date format is a standardized way of representing dates and times. To convert an ISO 8601 date to a different format in PHP, you can use the DateTime class to parse the ISO date string and then format it using the desired format using the format() method.

$isoDate = "2022-01-15T12:30:45Z";
$dateTime = new DateTime($isoDate);
$newFormat = $dateTime->format('Y-m-d H:i:s');
echo $newFormat;
