In PHP, both ISO8601 and ISO8601_EXPANDED formats are used for representing date and time in a standardized form. However, there are some differences between the two:
ISO8601 format uses a simplified version of the basic format, whereas ISO8601_EXPANDED includes all elements of the basic format.
ISO8601 format uses a single "T" to separate date and time values, whereas ISO8601_EXPANDED uses separate delimiter characters for each element.
ISO8601 format allows for variations in the number of digits used for elements such as milliseconds or time zone offset, whereas ISO8601_EXPANDED has a fixed number of digits for each element.
ISO8601_EXPANDED format includes additional delimiters to make the format easier to read and parse.
Overall, ISO8601_EXPANDED format provides a more detailed and comprehensive representation of date and time values, whereas ISO8601 format is simpler and more compact.
