How to use php to implement short URL jump? This article mainly introduces the implementation method of PHP short URL conversion, involving the operation skills of URLs and strings, and has certain reference value. I hope to be helpful!

From yesterday afternoon to now, I have overturned one information storage solution after another, from mysql to file_get_contents with unlimited memory, to fscanf for formatted input, and finally chose the more mature and stable read ini method.

The entire main program has only two files zipurl.php and index.php

zipurl.php file is as follows:

<?php   
//此文件用于转换url  
//整理url  
function dealurl($url)  
{  
    if($url[4]!=&#39;:&#39;)$url=&#39;http://&#39;.$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[&#39;url&#39;])  
    {  
        $url=dealurl($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">  
<p class="am-g">  
  <p 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>  
      <p><button type="submit" class="am-btn am-btn-primary am-btn-block">转换</button></p>  
    </form>  
  </p>  
</p>

## The #index.php file is as follows:

<?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[&#39;QUERY_STRING&#39;])  
    echo &#39;<script language="javascript">location.href="&#39;.readfiles($str).&#39;";</script>&#39;;  
}  
main();  
//统计部分  
?>  
<meta charset="utf-8">  
<title>ZIP your URL</title>  
<link rel="stylesheet" href="assets/css/amazeui.min.css">  
<p class="am-g">  
  <p 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>  
  </p>
