for each row of the two-dimensional array that prints the largest number and for each column the smallest number

As Jonathan told you, it is good to write the problem on paper and try to make a pseudo-code to have a clearer solution.
Anyway, I would probably use array_column instead.

foreach($array as $key => $subarray){
    $vals = array_column($subarray, $key)
    $min = min($vals);
    $max = max($vals);
}

and so you could get the lowest and highest of each one.
I have not tried the code with your array, but I feel that the index to be a String ("1", "2" ...) may give you problems.
In the case of a problem with that index in String, you would have to go through each list and compare each value with the other.
I hope that what I already showed you will help you solve the problem of your task.
