(PECL pht >= 0.0.1)
pht\Vector::insertAt — Inserts a value into the vector
说明
public pht\Vector::insertAt
( mixed $value
, int $offset
) : void
This method inserts a value at the specified offset into the vector (in linear time). The vector will automatically be resized if it is not large enough.
参数
value
- The value to be inserted into the vector. This value will be serialised (since it may be passed around between threads).
offset
- The offset at which the value will be inserted at. This offset must be within the 0..N range (inclusive), where N is the size of the vector. Inserting at position N is the equivalent of using pht\Vector::push(), and inserting at position 0 is the equivalent of using pht\Vector::unshift(). Attempting to insert at offsets outside of this range will result in an Error exception.
返回值
No return value.
范例
Example #1 Inserting a value into a vector
<?phpuse pht\Vector;$vector = new Vector();$vector->insertAt(3, 0); // insert 3 at start$vector->insertAt(1, 0); // insert 1 at start (before 3)$vector->insertAt(2, 1); // insert 2 in middle (after 1 and before 3)var_dump($vector);
以上例程会输出:
object(pht\Vector)#1 (3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) }
