如何为数组中的每个数组编写代码

Question

I am new to this so please do not judge.

1. I have transformed a .csv file into an array([0]=>array([0]=>string(), [1]=>string())[1]=>array([0]=>string(), [1]=>string()) etc. So I can access it numerically i.e. $the_big_array[1][1]

2. Now I want the program to write a couple of lines of code for each array within an array.

3. Basically what I am doing is creating a table like this that will be encoded in json.

   $request['AddPrice'][0][variable1] = $the_big_array[1][2] $request['AddPrice'][0][variable2] = $the_big_array[1][3]

and I want different values loaded for and from each line of .csv file/$the_big_array

$request['AddPrice'][1][variable1] = $the_big_array[1][2]
$request['AddPrice'][1][variable2] = $the_big_array[1][3]

I am stuck at foreach function as I cannot grasp how to make it execute certain action for each array within an array.

Answer 1

You have to use a foreach loop for every array dimension. If You have 2 dimensions, like in $the_big_array[1][1], go through the first dimension with your first loop. Inside this loop, do another foreach to go through your second dimension.
