PHP | Ds\Vector rotate()函数
Ds\Vector::rotate()函数是PHP中的一个内置函数,用于将数组元素旋转给定的旋转次数。旋转也发生在原地。
句法:
void public Ds\Vector::rotate( $rotations )
参数:此函数接受单个参数$rotations保存旋转次数。
返回值:此函数不返回任何值。
下面的程序说明了PHP中的Ds\Vector::rotate()函数:
方案一:
rotate(3);
echo("\nVector after rotating by 3 places\n");
// Display the Vector elements
print_r($vect);
?>
输出:
Original Vector
Ds\Vector Object
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
)
Vector after rotating by 3 places
Ds\Vector Object
(
[0] => 4
[1] => 5
[2] => 1
[3] => 2
[4] => 3
)
程序2:当旋转次数大于向量中的元素数时。
rotate(6);
echo("\nVector after rotating by 6 places\n");
// Display the Vector elements
print_r($vect);
?>
输出:
Original Vector
Ds\Vector Object
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
)
Vector after rotating by 6 places
Ds\Vector Object
(
[0] => 2
[1] => 3
[2] => 4
[3] => 5
[4] => 1
)
