What are the potential issues with dynamic URLs in PHP websites?

Dynamic URLs in PHP websites can cause issues with search engine optimization (SEO) as they may not be as easily indexed by search engines. To solve this issue, you can implement URL rewriting using Apache's mod_rewrite module to create user-friendly and SEO-friendly URLs. 

// .htaccess file
Options +FollowSymLinks
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
