PHP: 'rotate' an array?

Question

is it possible to easily \'rotate\' an array in PHP ?

Like this: 1, 2, 3, 4 -> 2, 3 ,4 ,1

Is there some kind of built-in PHP function for this?

Answer 1

$daynamesArray = array("Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday");
array_push($daynamesArray, array_shift($daynamesArray)); //shift by one
array_push($daynamesArray, array_shift($daynamesArray)); //shift by two
print_r($daynamesArray);

The output starts at "Wednesday":

Array ( [0] => Wednesday [1] => Thursday [2] => Friday [3] => Saturday [4] => Sunday [5] => Monday [6] => Tuesday
