In this tutorial you will learn how to:
Make Cookies.
Use Cookies.
Check for of Cookies.
Delete Cookies.

Remember: You cannot put Any html code before the code of the cookies!

Firstly you must learn how to set a cookie.
The order of it is: setcookie(name, value, expire);.
example:

Code:

$time = time();
$text = "This is what the cookie will hold";
setcookie(Name, $text, $time+3600);

And that is how you set a cookie!

Now to call a cookie to a script:
You can use:

Code:

echo "Your Cookies Value: ".$_COOKIE[Name];

That will then output:

Quote:

Your Cookies Value: This is what the cookie will hold

You can also use it to check for values.

Code:

if (isset($_COOKIE[name])){
echo "You have a cookie!"; }
else {
echo "You have no cookies!"; }

That will either return TRUE, if you have a cookie or FALSE if you dont.
Now you know how to use cookies.

Now onto deleting cookies.
Its a good idea to check if there is a cookie first before deleting.
Example:

Code:

$time = time();
if (isset($_COOKIE[name])){
setcookie(Name, '', $time-3600);  }
else {
echo "You have no cookies to delete!"; }

It may look like we are making another cookie, but we are just adjusting to cookie to expire immediately!
You just you - to set the cookie back to expire.

Now we will make a test script using what you have just learned.

We open the script and then check if the form is posted.
if the post is "Submit" create a cookie, else if the post is "Reset" be delete it.

Code:

<?php
if ($_POST['Submit']){
setcookie(id,'kis works',time()+3600);
echo "Cookie Made!"; }
if ($_POST['Reset']){
if (isset($_COOKIE[id])){
setcookie(id,'',time()-3600);
echo "Deleted!"; }
else {
echo "You have no such cookie to delete!"; } }

Now we will make a form with two buttons.

Code:

echo "<form name='form1' method='post' action=''>
  <label></label>
  <label>
  <input type='submit' name='Submit' value='make'>
    <input type='submit' name='Reset' value='delete'>
  </label>
</form>
<br />";

Now we will display the cookie's value if it exists.

Code:

echo "Previous Attempts: ";
if (isset($_COOKIE[id])){
echo $_COOKIE[id]; }
else {
echo "None"; }

Now we close the script.

Code:

?>

You now know how to make, use and delete cookies!

The complete script:

Code:

<?php
/*
>> Basic Cookies Tutorial
*/
if ($_POST['Submit']){
setcookie(id,'kis works',time()+3600);
echo "Cookie Made!"; }
if ($_POST['Reset']){
if (isset($_COOKIE[id])){
setcookie(id,'',time()-3600);
echo "Deleted!"; }
else {
echo "You have no such cookie to delete!"; } }
echo "<form name='form1' method='post' action=''>
  <label></label>
  <label>
  <input type='submit' name='Submit' value='make'>
    <input type='submit' name='Reset' value='delete'>
  </label>
</form>
<br />";
echo "Previous Attempts: ";
if (isset($_COOKIE[id])){
echo $_COOKIE[id]; }
else {
echo "None"; } 
?>
