PHP | Ds\Vector remove() Function
The Ds\Vector::remove() function is an inbuilt function in PHP which is used to reverse the elements of the vector in-place. For example, if the vector elements are [1, 2, 3, 4, 5], then it will be reversed as [5, 4, 3, 2, 1].
Syntax:
mixed public Ds\Vector::remove( $index )
Parameters: This function does not accept any parameter.
Return Value: This function does not return any value.
Below programs illustrate the Ds\Vector::remove() function in PHP:
Program 1:
<?php // Declare new Vector$arr = new \Ds\Vector([1, 2, 3, 4, 5, 6]); echo("Vector Elements\n"); // Desplay the Vector elementsvar_dump($arr); // Use reverse() function to // reverse Vector elements$arr->reverse(); echo("\nVector after reversing\n"); // Display the vector elementsvar_dump($arr); ?> |
Output:
Vector Elements
object(Ds\Vector)#1 (6) {
[0]=>
int(1)
[1]=>
int(2)
[2]=>
int(3)
[3]=>
int(4)
[4]=>
int(5)
[5]=>
int(6)
}
Vector after reversing
object(Ds\Vector)#1 (6) {
[0]=>
int(6)
[1]=>
int(5)
[2]=>
int(4)
[3]=>
int(3)
[4]=>
int(2)
[5]=>
int(1)
}
Program 2:
<?php // Declare new Vector$vect = new \Ds\Vector(["Learn", "data", "structures"]); echo("Vector Elements\n"); // Desplay the Vector elementsprint_r($vect); // Use reverse() function to // reverse Vector elements$vect->reverse(); echo("\nVector after reversing\n"); // Display the vector elementsprint_r($vect); ?> |
Output:
Vector Elements
Ds\Vector Object
(
[0] => Learn
[1] => data
[2] => structures
)
Vector after reversing
Ds\Vector Object
(
[0] => structures
[1] => data
[2] => Learn
)
