Determing The Day From A DateTime String.

[Vermillion]

Suppose I have the following DateTime string.

 

20100312122636

 

How can I determine what day is it based on it? I want to know what day (Sunday, Monday, Tuesday...) is based on that string, but I can't figure a way to do it.

You'll need to convert that into something usable by PHP's date funtions and from there it is easy to get the day of the week.  For example (the following could be mushed onto one line, it is split up for ease of understanding):

 

$date = '20100312122636';

// Grab date parts
$year  = substr($date, 0, 4);
$month = substr($date, 4, 2);
$day   = substr($date, 6, 2);

// Get the UNIX timestamp for the date
$timestamp = gmmktime(0, 0, 0, $month, $day, $year);

// Print the day of week
echo date('l', $timestamp);
