(PECL ds >= 1.0.0)
Ds\Vector::rotate — Rotates the vector by a given number of rotations
Description
public Ds\Vector::rotate
( int $rotations
) : void
Rotates the vector by a given number of rotations, which is equivalent
to successively calling $vector->push($vector->shift()) if the number
of rotations is positive, or $vector->unshift($vector->pop()) if negative.
Parameters
rotations- The number of times the vector should be rotated.
Return Values
No value is returned.. The vector of the current instance will be rotated.
Examples
Example #1 Ds\Vector::rotate() example
<?php$vector = new \Ds\Vector(["a", "b", "c", "d"]);$vector->rotate(1); // "a" is shifted, then pushed.print_r($vector);$vector->rotate(2); // "b" and "c" are both shifted, the pushed.print_r($vector);?>
The above example will output something similar to:
(
[0] => b
[1] => c
[2] => d
[3] => a
)
Ds\Vector Object
(
[0] => d
[1] => a
[2] => b
[3] => c
)
