                                    setcookie(&quot;cookiename&quot;, &quot;cookievalue&quot;, time(), &quot;.mydomain.tld&quot;, &quot;/&quot;)

// coookiename: The name of your cookie
// cookievalue: The value of your cookie
// Time: The expiration date of your cookie. If you plan to make a product for the EU, it's 13 months max.
// .mydomain.tld: The domain that your webpage is using. You can only use the domain that the PHP file is on. Adding a dot before your domain will cover all subdomains.
// &quot;/&quot;: This is the folder where your cookie will apply. If you want a specific cookie for the /mySpecialSuperSecretPages folder, you have to set /mySpecialSuperSecretPages
// Check the source for more options.
