set cookie(“y”, “Schools”, time()+3600)
echo $_COOKIE[x’];
echo $_COOKIE[‘y’];
?>
<a herf=”page2.php”>Go</a>
Every browser contains own memory locations Ram and hard disc, COOKIE information will store in that memory location. We cannot access cookies of one browser to another browser. The memory location of browser will destroy when user closed all windows of that browser
We can destroy persistent COOKIE before life time by recreating that COOKIE with completed time
<?php
set cookie(“abc”, ” “, time()-1);
echo $_COOKIE[‘abc’];
?>
