What resources or tutorials would you recommend for someone with limited PHP knowledge looking to implement universal links in their documents?

To implement universal links in documents using PHP, you will need to create a .htaccess file to redirect specific URLs to your desired destination. This will allow users to open links to your website directly in your app, if installed, instead of the browser.

RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} (iPhone|iPad)
RewriteCond %{REQUEST_URI} !/your-app-uri/
RewriteRule ^(.*)$ https://yourdomain.com/your-app-uri/$1 [L,R=301]
