写了一个简单的，可以应付一些简单的项目了。
以下是代码片段：<?php
/**
* TinyURL生成类
*
* @link http://skiyo.cn
* @author Jessica

*/
class TinyURL {
/**
* 组成URL的大小写字母
*
* @var array
*/
protected $alpha = array();
/**
* 数组数量
*
* @var int
*/
protected $count = 0;
/**
* 构造器 生成URL数组
*
* @access public
*/
public function __construct() {
$this->alpha = array_merge(range(0, 9), range(’a’, ’z’), range(’A’, ’Z’));
$this->count = count($this->alpha);
}
/**
* 通过数字生成唯一的URL
*
* @param int $num
* @return string
*/
public function getURL($num) {
$num = (int)$num;
$url = ’’;
while($num >= 1) {
$url .= $num < $this->count ? $this->alpha[$num] : $this->alpha[$num%$this->count];
$num = (int)($num)/$this->count;
}
$url = strrev($url);
return $url;
}
}
/**
* @example
*/
$t = new TinyURL();
for($i=1;$i<=10000;$i++) {
echo $t->getURL($i). ’<br />’;
}
