Setting and Reading Cookies Across Pages with PHP and JavaScript

When attempting to set a cookie with JavaScript and access it from a different PHP page, it may be necessary to address domain and path settings.

In JavaScript, to set a cookie with a specific expiration date, domain, and path:

<code class="js">function createCookie(name, value, days) {
  const date = new Date();
  date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
  const expires = "; expires=" + date.toGMTString();
  const domain = "; domain=.example.com";
  const path = "; path=/";
  document.cookie = name + "=" + value + expires + domain + path;
}</code>

Ensure that the domain and path match the target page. For example, if the cookie is set on example.com/index.php and needs to be accessed on example.com/test.php, the settings should be:

<code class="js">createCookie('cookieee', 'stuff', 22);</code>

In PHP, access the cookie using $_COOKIE:

<code class="php"><?php 
  print_r($_COOKIE);
?></code>
