How to implement php short address conversion, php conversion

The example in this article describes the implementation method of PHP short address conversion. Share it with everyone for your reference. The specific analysis is as follows:

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 a more mature and stable method of reading ini. .

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

zipurl.php file is as follows:

Copy code The code is as follows:

//This file is used to convert url
//Organize 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 $tmp;
}
//Save account
function zipurl($urls)
{
//Directory check and duplicate removal
$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=%sr",$num,$urls);
fclose($handle);
Return $num;
}
function main()
{
If($url=$_GET['url'])
{ 
$url=dealurl($url);
          $url=zipurl($url);
echo "http://localhost/?".$url;
}  
}
main();
?>

           

Convert

The index.php file is as follows:

Copy code The code is as follows:

//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 ''; 
} 
main(); 
//统计部分 
?> 
 
 
 

 
 

 
   

 
     

 
         
     

 
      转换
