format date?

[nikko50]

Hi all.
If I had a date string like this "20061231". Is there a built in functions to format this to something like "Sunday, December 31, 2006"

You could try:

<?php
$date = "20061231";
echo date('l, F d, Y', strtotime($date));
?>

Thanks laserlight. One last question.
How can I tell if the string is a valid date?
Happy New Year!

Use [man]checkdate/man by extracting the month, day and year:

function isValidDate($date) {
    return strlen($date) == 8
        && checkdate(substr($date, 4, 2),
                     substr($date, 6),
                     substr($date, 0, 4));
}

Oh, and happy new year to you too!
