// Create a new vector $vect = new DsVector ([1, 2, 3, 4, 5]);  
// Show vector elements print_r ( $vect );  
// Use the set() function to set
// element in vector $vect -> set (1, 10); echo ( " Vector after updating the element " );  
// Show vector elements print_r ( $vect );  
?> Output:

DsVector Object ([0] = > 1 [1] = > 2 [2] = > 3 [3] = > 4 [4] = > 5) Vector after updating the element DsVector Object ([0] = > 1 [1] = > 10 [2] = > 3 [3] = > 4 [4] = > 5)

Program 2:  
// Create a new vector $vect = new DsVector ([ "engineer" , "of" , "engineer" ]);  
// Show vector elements print_r ( $vect );  
// Use the set() function to set
// element in vector $vect -> set (1, "for" ); echo ( " Vector after updating the element " );  
// Show vector elements print_r ( $vect );  
?> Output:

DsVector Object ([0] = > engineer [1] = > of [2] = > engineer) Vector after updating the element DsVector Object ([0] = > engineer [1] = > for [2] = > engineer)
