Assignment:3 Set A Q.1 Solution

Q.1. Write PHP program to perform the following operations on Indexed Array: a) Union of two arrays b) Traverse the array elements in random order

    
      <?php

  //input string 1

  echo"Enter Elements of Array 1 (Saperate them with a ,)";

  $inp1= readline();

  

  //input string 2

  echo"Enter Elements of Array 2 (Saperate them with a ,)";

  $inp2= readline();

  

  //convert both input into array

  $arr1= explode(',',$inp1);

  

  $arr2= explode(',',$inp2);

  

  //UNION OF ARRAYS

  //Step 1: merge 2 arrays

  

  $arr3= array_merge($arr1,$arr2);

  

  $arr3= array_unique($arr3);

  

  echo"Union of Arrays:\n";

  print_r($arr3);

  

  //SHUFFLING

 shuffle($arr3);

  

  echo"Shuffled Aray Elements:\n";

  foreach($arr3 as $element)

  {

     echo"$element\n"; 

  }

?>
