?> Output:Vector Elements DsVector Object ([0] = > engineer [1] = > for [2] = > engineer [3] = > DataStructures) Last element of the vector: string (14) "DataStructures "
Program 2:
// Declare a new vector $vect = new DsVector ([1, 2, 3, 4 , 5, 6]); echo ( " Vector Elements " );
// Show vector elements print_r ( $vect ); echo ( " Last element of the vector: " );
// Use the remove() function to remove
// value at index 3 and return it var_dump ( $vect -> remove (3));
