如何将长数组转换为字符串数组？

long_array = [123456789, 987654321, 1112131415]
string_array = [str(num) for num in long_array]

const longArray = [123456789, 987654321, 1112131415];
const stringArray = longArray.map(num => num.toString());

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List<Long> longArray = Arrays.asList(123456789L, 987654321L, 1112131415L);
        List<String> stringArray = new ArrayList<>();
        for (Long num : longArray) {
            stringArray.add(num.toString());
        }
    }
}

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<long> longArray = new List<long> { 123456789, 987654321, 1112131415 };
        List<string> stringArray = new List<string>();
        foreach (long num in longArray)
        {
            stringArray.Add(num.ToString());
        }
    }
}

$longArray = [123456789, 987654321, 1112131415];
$stringArray = array_map(function($num) {
    return strval($num);
}, $longArray);
