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 elements var_dump( $arr ); // Use reverse() function to // reverse Vector elements $arr ->reverse(); echo ( "\nVector after reversing\n" ); // Display the vector elements var_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 elements print_r( $vect ); // Use reverse() function to // reverse Vector elements $vect ->reverse(); echo ( "\nVector after reversing\n" ); // Display the vector elements print_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 )
