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urlfunction 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();?><meta charset="utf-8"><title>ZIP your URL</title><link rel="stylesheet" href="assets/css/amazeui.min.css"><div class="am-g">  <div class=" col-md-8 col-sm-centered">    <form class="am-form" action="zipurl.php" method="get">      <fieldset class="am-form-set">        <input type="text" id="url" name="url" placeholder="输入你想转换的网址">      </fieldset>      <div><button type="submit" class="am-btn am-btn-primary am-btn-block">转换</button></div>    </form>  </div>
</div>

index.php

<?php #查号 #短址访问部分function readfiles($strs){	$array=parse_ini_file("url.tmp",true);	var_dump($array);	return $array[$strs];}function main(){	#转到模块	if($str=$_SERVER['QUERY_STRING'])	echo '<script language="javascript">location.href="'.readfiles($str).'";';}main();#统计部分?><meta charset="utf-8"><title>ZIP your URL</title><link rel="stylesheet" href="assets/css/amazeui.min.css"><div class="am-g">  <div class=" col-md-8 col-sm-centered">    <form class="am-form" action="zipurl.php" method="get">      <fieldset class="am-form-set">        <input type="text" id="url" name="url" placeholder="输入你想转换的网址">      </fieldset>      <button type="submit" class="am-btn am-btn-primary am-btn-block">转换</button>    </form>  </div>
