Super simple code for php short URL
System environment:
php, apache2, linux

Operation to generate php short URL:
Copy the code to index.php and put it in a folder name with only 1 character (such as u) in the secondary directory.
Add write permissions to this directory. To save trouble, just chmod 777 u (the root directory is also OK, you may need to change the code to avoid affecting other files)

The URL generation result:
Put http://www.heimaolianmeng.com/ heimaoseojishu/ becomes http://127.0.0.1/u/1
The principle of php generating short URL:
1. Get the url to be shortened through form post
2. Put the url in a javascript and write it to the file. Names grow by numbers. The function of javascript is to jump to the specified url

Optimization:
If you can set a second-level domain name, just point the second-level domain name to that directory, and there is no need to enter an extra u/.

Code:


Code example:



Shorten URL


URL to be shortened: (must include protocol like http:// or https:// etc.)







if (isset($_POST['url'])) {
$origin = $_POST['url'];
if (strlen($origin) > 10) {
$filename = count(scandir('.')) - 3; // strip php self . ..
file_put_contents($filename,
'');
$shortened = "http://". $_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF']).'/'.$filename;
echo 'Original URL is
'.$origin.'
'
.'Shortened URL is
'.$shortened.'';
} else {
echo "The URL you entered is NOT valid.";
}
}
?>


Generate a file with a number as the file name:
