How to use Ds\Vector copy() function in PHP?

DsVector::copy() function is a built-in function in PHP that is used to create a copy of a given vector.

The syntax is as follows:

DsVector public DsVector::copy( void )
  • Parameters: This function does not accept any parameters.

  • Return value: This function returns a shallow copy of the vector.

The following program illustrates the usage of the DsVector::copy() function in PHP:

Program 1:

<?php
  
// Create a vector array
$arr1 = new DsVector([1, 2, 3, 5]);
  
// Use copy() function to copy
// the vector array
$arr2 = $arr1 -> copy ();
  
echo ( "Original Array n" );
  
// Display the original array
print_r( $arr1 );
  
echo ( "Copied Array n" );
  
// Display the copied array
print_r( $arr2 );
  
?>

The output is as follows:

Original Array 
DsVector Object
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 5
)
Copied Array 
DsVector Object
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 5
)

Program 2:

<?php
  
// Create a vector array
$arr1 = new DsVector([ "geeks" , "for" , "geeks" ]);
  
// Use copy() function to copy
// the vector array
$arr2 = $arr1 -> copy ();
  
echo ( "Original Arrayn" );
  
// Display the original array
print_r( $arr1 );
  
echo ( "Copied Arrayn" );
  
// Display the copied array
print_r( $arr2 );
  
?>

The output is as follows:

Original Array
DsVector Object
(
    [0] => geeks
    [1] => for
    [2] => geeks
)
Copied Array
DsVector Object
(
    [0] => geeks
    [1] => for
    [2] => geeks
)
