Need Single multidimensional array Like

Array ( 

    [0] => Array ( [student_id] => 1190101 [stname] => Student 1 [remarks] => 1 [totals] => 21 ) 

    [1] => Array ( [student_id] => 1190102 [stname] => Student 2 [remarks] => 1 [totals] => 6 ) 

    [2] => Array ( [student_id] => 1190103 [stname] => Student 3 [remarks] => [totals] => 11 ) 

    [3] => Array ( [student_id] => 1190104 [stname] => Student 4 [remarks] => 1 [totals] => 6*[totals] => 5* ) 

    [4] => Array ( [student_id] => 1190105 [stname] => Student 5 [remarks] => 1 [totals] =>4 [totals] => 5 ) 

    [5] => Array ( [student_id] => 1190106 [stname] => Student 6 [remarks] => 1 [totals] => 6[totals] => 5 ) 

    [6] => Array ( [student_id] => 1190107 [stname] => Student 7 [remarks] => 1 [totals] => 6 [totals] => 5 ) 

    [7] => Array ( [student_id] => 1190108 [stname] => Student 8 [remarks] => 1 [totals] => 6 ) 

    [8] => Array ( [student_id] => 1190109 [stname] => Student 9 [remarks] => 1 [totals] => 6 [totals] => 5 ) 

    [9] => Array ( [student_id] => 1190110 [stname] => Student 10 [remarks] => 1 [totals] => 6 ) 

)

My Answer:
"Math Exam",
[1] = "Science Exam",
[2] = "History Exam",
[3] = "English Exam"
)

Array 2_Array (
[0] = "Math Exam",
[1] = "Art Exam",
[2] = "History Exam",
[3] = "Geography Exam"
)

Merged Array (
[0] = "Math Exam",
[1] = "Science Exam",
[2] = "History Exam",
[3] = "English Exam",
[4] = "Art Exam",
[5] = "Geography Exam"
)
