How can i use file_exists function for the cookie (like if cookie exists).

And then i want to show the cookie on the screen.
I am using echo "$cookie_name"; but it isn't working!

Please help me

Instead of file_exists, I would just check if anything is stored in $cookie_name.

Example,
<?php
if ($cookie_name != "") { //cookie is not blank
do something(?);
}
else { //set the cookie
setcookie("cookie_name", $value, time());
}
?>
