Ever wonder how to create a download link in PHP and then make it expire? Would you like to know how to expire a download link after a set number of times they download it? Do you want to know how to protect your files from people trying to steal your downloads? We are going to answer those questions and more on this tutorial.
Setting Up The Database For Expired Links
Set up your database first. Create a database and then use the following code to set up the table and rows. Let me tell you what each row is going to do. The link row is going to save an encrypted link that you will use for your application. This will appear in the URL address bar. The file is going to be the name of the file you are uploading for a user to download. The counting row is going to keep track of how many times you allow a file to be downloaded. The expire row is going to keep track of the time you set for the link to expire. The tstamp row is going to keep track of the time that you uploaded the file.
CREATE TABLE `links` ( `id` int(11) NOT NULL, `link` char(40) NOT NULL, `file` text NOT NULL, `counting` int(11) NOT NULL DEFAULT 11, `expire` int(11) NOT NULL, `tstamp` int(10) UNSIGNED NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;;
