title: php setcookie not working with ajax call
body: <p>I have a page, test.php, with the following code:</p>
  
  <pre><code>&lt;html&gt;
      &lt;body&gt;
          &lt;form&gt;
              &lt;script type="text/javascript"&gt; 
  
                  function SendCookies(){
  
                      if (window.XMLHttpRequest)/* code for IE7+, Firefox, Chrome, Opera, Safari */
                      { xmlhttp=new XMLHttpRequest(); }
                      else /* code for IE6, IE5 */
                      { xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); }
  
                      xmlhttp.onreadystatechange=function()
                      {
                          if (xmlhttp.readyState==4 &amp;&amp; xmlhttp.status == 200)
                          {
                              alert('done');
                          }
                      }
  
                      xmlhttp.open("GET", "/web/DEV/Classes/SetCookie.php?time=" + new Date());
                      xmlhttp.send();
  
                  }
  
              &lt;/script&gt;
  
              &lt;input type="text" id="txtInput" name="txtInput"/&gt;
              &lt;input type="button" id="btnSubmit" name="btnSubmit" value="Submit"  onclick="SendCookies()"/&gt;
              &lt;div id="divTest"&gt;
                  &lt;?php
                      if (isset($_COOKIE["TestCookie"])) {
                          echo $_COOKIE["TestCookie"];
                      } else {
                          echo "__Results__";
                      }
                  ?&gt;          
              &lt;/div&gt;
          &lt;/form&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I have a page, SetCookie.php, with the following code:</p>
  
  <pre><code>&lt;?php 
      $var = "THIS IS  A  TEST";
      setcookie("TestCookie", $var, time()+60*60*24*30);
  ?&gt;
  </code></pre>
  
  <p>When test.php's button is clicked, i use XMLHttpRequest to call my SetCookie.php page.  The page executes, becuase if i add an echo to it, i get that in the xmlhttp response.  However, TestCookie does not seem to be getting set.</p>
  
  <p>If in text.php, i do the same command found in SetCookie.php, the cookie is then set accordingly for all browser sessions.</p>
  
  <p>Even after i close / open the browser, the cookie remains unchanged from when i once set it in my test.php page manually.</p>
  
  <p><strong>----EDIT-----</strong></p>
  
  <p>I added:</p>
  
  <pre><code>if(!setcookie("TestCookie", "A", time()+60*60*24*30, "/")) {
      echo "FAIL";
  }
  </code></pre>
  
  <p>to the very top of test.php, however when i reload the page, it never shows the updated cookie... <strong>because that cookie was already set without the ,"/" parameter, and cannot be modified later, with the ,"/" parameter.</strong></p>
  
  <p>After clearing the cache and working with the suggested code, i cleared my cookies from the browser and used the added parameter for the set method, i was able to manipulate the cookies from all pages!!! thank you so much!!</p>
