title: setcookie("user", "", time()-3600) not working
body: <p>I tried to use <code>setcookie("user", "", time()-3600)</code> to delete a cookie from php, but it's not working for me, when I check in the tool of the broswer, the cookie seems to still exist. Does anyone know why? </p>
  
  <p>note: this is the domain cookies.. mean I set this cookies with this way <code>setcookie('user','true',time() + 2592000,"/",".user.com",0);</code></p>
