pht\Vector::deleteAt
(PECL pht >= 0.0.1)
pht\Vector::deleteAt — Deletes a value in the vector
说明
public pht\Vector::deleteAt
( int $offset
) : void
This method deletes a value at the specified offset in the vector (in linear time).
Since the pht\Vector class supports array access,
deleting values can also be performed using the array subset notation
([]
) in combination with the unset()
function.
参数
offset
- The offset at which the value will be deleted at. This offset must be within the 0..(N-1) range (inclusive), where N is the size of the vector. Attempting to delete at offsets outside of this range will result in an Error exception.
返回值
No return value.
范例
Example #1 Deleting values in a vector
<?phpuse pht\Vector;$vector = new Vector();$vector[] = 1;$vector[] = 2;$vector[] = 3;$vector[] = 4;$vector->deleteAt(1);unset($vector[1]);var_dump($vector);
以上例程会输出:
object(pht\Vector)#1 (2) { [0]=> int(1) [1]=> int(4) }
