Randomize array

How Would I randomize this Array So that when i use a for each loop it would it would switch index 0 with key 1 and to randomize the order

iv tried $variable= array_rand($varialbe,count($variavle)) but it prints out

  0 => int 0
  1 => int 1
  2 => int 2
  3 => int 3
  4 => int 4

foreach ($variable as $key)

    array (size=10)
          0 => 
            object(stdClass)[25]
              public 'id' => string '24' (length=2)
              public 'course_name' => string 'Office Automation' (length=17)
              public 'test_name' => string 'Test 2' (length=6)
              public 'total_questions' => string '10' (length=2)
              public 'duration' => string '20' (length=2)
              public 'total_marks' => string '20' (length=2)
              public 'question' => string 'Question1' (length=9)
              public 'option1' => string 'ans1' (length=4)
              public 'option2' => string 'ans2' (length=4)
              public 'option3' => string 'ans3' (length=4)
              public 'option4' => string 'ans4' (length=4)
              public 'ans' => string 'D' (length=1)
              public 'count' => string '1' (length=1)
          1 => 
            object(stdClass)[26]
              public 'id' => string '25' (length=2)
              public 'course_name' => string 'Office Automation' (length=17)
              public 'test_name' => string 'Test 2' (length=6)
              public 'total_questions' => string '10' (length=2)
              public 'duration' => string '20' (length=2)
              public 'total_marks' => string '20' (length=2)
              public 'question' => string 'Question2' (length=9)
              public 'option1' => string 'ans1' (length=4)
              public 'option2' => string 'ans2' (length=4)
              public 'option3' => string 'ans3' (length=4)
              public 'option4' => string 'ans4' (length=4)
              public 'ans' => string 'A' (length=1)
              public 'count' => string '2' (length=1)
          2 => 
            object(stdClass)[27]
              public 'id' => string '26' (length=2)
              public 'course_name' => string 'Office Automation' (length=17)
              public 'test_name' => string 'Test 2' (length=6)
              public 'total_questions' => string '10' (length=2)
              public 'duration' => string '20' (length=2)
              public 'total_marks' => string '20' (length=2)
              public 'question' => string 'Question3' (length=9)
              public 'option1' => string 'ans1' (length=4)
              public 'option2' => string 'ans2' (length=4)
              public 'option3' => string 'ans3' (length=4)
              public 'option4' => string 'ans4' (length=4)
              public 'ans' => string 'B' (length=1)
              public 'count' => string '3' (length=1)

How Would i do That

Need to just randomize the order so that when it prints it will print a new order everytime

The array stores question and question option in the keys/indexes
