Merge a multi-dimensional array to the custom array as required. Need the solution in PHP (using in Laravel-8). Custom array is needed to make rows for creating an excel file using Spreadsheet. This is the Original array I have =
array:3 [
0 => array:4 [
0 => array:3 [
0 => "Name"
1 => "English"
2 => "Math"
]
1 => array:3 [
0 => "John"
1 => 10
2 => 20
]
2 => array:3 [
0 => "Doe"
1 => 20
2 => 30
]
3 => array:3 [
0 => "Smith"
1 => 30
2 => 50
]
]
1 => array:4 [
0 => array:3 [
0 => "Name"
1 => "Science"
2 => "Hindi"
]
1 => array:3 [
0 => "John"
1 => 10
2 => 20
]
2 => array:3 [
0 => "Doe"
1 => 20
2 => 57
]
3 => array:3 [
0 => "Smith"
1 => 30
2 => 89
]
]
2 => array:4 [
0 => array:3 [
0 => "Name"
1 => "ABC"
2 => "XYZ"
]
1 => array:3 [
0 => "John"
1 => 10
2 => 20
]
2 => array:3 [
0 => "Doe"
1 => 20
2 => 23
]
3 => array:3 [
0 => "Smith"
1 => 30
2 => 89
]
]
]
From the above array need to make the array like below (array size may very, so need dynamic solutions) -
array:1 [
0 => array:4 [
0 => array:7 [
0 => "Name"
1 => "English"
2 => "Math"
3 => "Science"
4 => "Hindi"
5 => "ABC"
6 => "XYZ"
]
1 => array:7 [
0 => "John"
1 => 10
2 => 20
3 => 10
4 => 20
5 => 10
6 => 20
]
2 => array:7 [
0 => "Doe"
1 => 20
2 => 30
3 => 20
4 => 57
5 => 20
6 => 23
]
3 => array:7 [
0 => "Smith"
1 => 30
2 => 50
3 => 30
4 => 89
5 => 30
6 => 89
]
]
]
