This article describes how to implement php short address conversion. Share it with you for your reference. The specific analysis is as follows:

From yesterday afternoon to now I overturned one information storage solution after another, from mysql to file_get_contents with unlimited memory, and then to formatting the input fscanf ,, finally, we chose a mature and stable method for reading ini.

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

The zipurl. php file is as follows:

The Code is as follows:

<? Php
// This file is used to convert the url
// Sort URLs
Function dealurl ($ url)
{
If ($ url [4]! = ':') $ Url = 'HTTP: // '. $ url;
Return $ url;
}
Function ranum ()
{
$ Str = "0123456789 abcdefghijklmnopqrstuvwxyz ";
$ 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 the number
Function zipurl ($ urls)
{
// Check the number for deduplication
$ 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 ();
?>

ZIP your URL

The index. php file is as follows:

The Code is as follows:

<? Php
// Check the ID
// Short address access part
Function readfiles ($ strs)
{
$ Array = parse_ini_file ("url. tmp", true );
Var_dump ($ array );
Return $ array [$ strs];
}
Function main ()
{
// Switch to the module
If ($ str = $ _ SERVER ['query _ string'])
Echo'
