php短址转换实现

从昨天下午到现在 推翻了一个又一个的信息存储方案，从mysql到加上内存不受限制的file_get_contents，再到格式化输入的fscanf，最终选择了比较成熟稳定的读取ini的方法。

整个主程序只有两个文件 zipurl.php、index.php

zipurl.php:

<?php 
#此文件用于转换url
#整理url
function dealurl($url)
{
	if($url[4]!=':')$url='http://'.$url;
	return $url;
}
function ranum()
{
$str="0123456789abcdefghijklmnopqrstuvwxyz";
$tmp=$str[mt_rand(0,35)].$str[mt_rand(0,35)].$str[mt_rand(0,35)].$str[mt_rand(0,35)].$str[mt_rand(0,35)];
return $tmp;
}
#存号
function zipurl($urls)
{
	#查号去重
	$handle = fopen("url.tmp","r+");
	$array=parse_ini_file("url.tmp",true);
	if(array_search($urls, $array))return array_search($urls, $array);
	$num=ranum();
	fprintf($handle,"%s=%s\r",$num,$urls);
	fclose($handle);
	return $num;
}
function main()
{
	if($url=$_GET['url'])
	{
		$url=dealurl($url);
		$url=zipurl($url);
		echo "http://localhost/?".$url;
	}

}
main();
