小编Sco*_*rad的帖子

Wordpress提供了一个名为"the_permalink()"的函数,它返回,你猜对了!,在一个帖子循环中,给定帖子的永久链接.

我正在尝试URL编码永久链接,当我执行此代码时:

<?php
print(the_permalink());
$permalink = the_permalink();
print($permalink);
print(urlencode(the_permalink()));
print(urlencode($permalink));
$url = 'http://wpmu.local/graphjam/2008/11/06/test4/';
print($url);
print(urlencode($url));
?>

它以HTML格式生成这些结果:

http://wpmu.local/graphjam/2008/11/06/test4/
http://wpmu.local/graphjam/2008/11/06/test4/
http://wpmu.local/graphjam/2008/11/06/test4/
http://wpmu.local/graphjam/2008/11/06/test4/
http%3A%2F%2Fwpmu.local%2Fgraphjam%2F2008%2F11%2F06%2Ftest4%2F

我希望输出的第2,3和5行是URL编码的,但只有第5行是这样的.思考？

看看它:这个小的.NET控制台程序会产生有趣的结果......请注意我是如何以两种不同的方式将浮点数转换为整数:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace CastVsConvert
{
    class Program
    {
        static void Main(string[] args)
        {
            int newWidth = 0;
            CalculateResizeSizes(600, 500, out newWidth);
        }

        static void CalculateResizeSizes(int originalWidth, int maxWidth, out int newWidth)
        {
            float percentage = 1.0F;
            percentage = maxWidth / (float)originalWidth;

            newWidth = (int)((float)originalWidth * percentage);
            int newWidthConvert = Convert.ToInt32((float)originalWidth * percentage);

            Console.Write("Percentage: {0}\n", percentage.ToString());
            Console.Write("Cast: {0}\n", newWidth.ToString());
            Console.Write("Convert: {0}\n", newWidthConvert.ToString());
        }
    }
}

我希望"Cast"和"Convert"的输出相同,但它们不是......这是输出:
