Are there any best practices for converting date strings to ISO 8601 format in PHP to ensure accurate timestamp conversion?

When converting date strings to ISO 8601 format in PHP, it is important to ensure that the date string is in a format that PHP's DateTime class can recognize. One common approach is to use the DateTime::createFromFormat() method to specify the format of the input date string before converting it to ISO 8601 format. This helps to ensure accurate timestamp conversion.

$dateString = "2022-10-15 14:30:00";
$date = DateTime::createFromFormat('Y-m-d H:i:s', $dateString);
$iso8601Date = $date->format('c');
echo $iso8601Date;
