สอบถามเรื่อง input ภาษา php ครับ เมื่อเทียบกับภาษา Java

public class sortApp {

    public static void main(String args[]) {
        int max = 0;
        int temp = 0;
        int range = 0;
        int z, k = 0;
        String lengthObj = "";
        //recieved input from keyboard
        Scanner input = new Scanner(System.in);
        int myNumber[] = new int[input.nextInt()];//first input specified the number of data set

        range = myNumber.length;
        //set each value to an arraylist
        for (int i = 0; i < myNumber.length; i++) {
            myNumber[i] = input.nextInt();
        }
        //check each variable against each other
        max = myNumber[0];
        for (int j = 1; j < range; j++) {
            if (max < myNumber[j]) {
                max = myNumber[j];
                lengthObj = (j + 1) + "";
            }
        }
        //check 1-2,1-2-3,....
        for (int m = 0; m <= range; m++) {
            for (k = 0; k <= range; k++) {
                for (z = m; z < k; z++) {
                    temp += myNumber[z];
                }
                if (max < temp) {
                    max = temp;
                    lengthObj = (m + 1) + "-" + z;
                }
                temp = 0;
