|Welcome back. Just to summarise - in the first part of the cookie tutorial, we learnt how to create cookies, how to give an expiry date to the cookie and how to print out specific cookies.
|-
|0:13
|Using this command here, we also learnt how to print out every cookie that we had stored.
|-
|0:18
|So assuming that we have created these cookies, the next thing I'll do is use this specific cookie here that I have created, to check whether it does exist or not.
|-
|0:28
|To do so, we will use a function called “isset”.
|-
|0:32
|This basically returns a true or false value depending on whether something is set or not.
|-
|0:37
|For example- a cookie ,I'll put a dollar sign then underscore cookie.
|-
|0:42
|And I'll put 'name' in here.
|-
|0:46
|So if I read this out in English language then I'll say -
|-
|0:49
|If the cookie name is set then we say echo “Cookie is set”.
|-
|0:57
|Otherwise we will echo out to the user that "Cookie is not set".
|-
|1:01
|Assuming that I have set my cookie and everything is working, when I refresh this I'll get the message that the "Cookie is set".
|-
|1:11
|Now I'll teach you how to 'unset' a cookie.
|-
|1:14
|So lets say over here - just before our 'if' statement, I wish to unset my cookie.
|-
|1:20
|So unset a cookie.
|-
|1:21
|So just to name one, I'll unset this cookie,
|-
|1:25
|presuming that if you learn to unset this one you can unset this one too.
|-
|1:31
|So I'll unset this name cookie.
|-
|1:34
|So to unset we use the same command and that’s 'setcookie'.
|-
|1:39
|So we are resetting a cookie.
|-
|1:41
|This doesn’t seem to make any sense but it will soon.
|-
|1:45
|Now we will set the cookie name to nothing.
|-
|1:49
|And our expiry date here...
|-
|1:51
|I'll create a new one with "exp unset"
|-
|1:55
|And that is gonna equal to the time minus 86400.
|-
|2:01
|Here we said plus which meant that the time is in the future.
|-
|2:05
|Now by setting the cookie to this variable which represents a time in the future, we are actually unsetting the cookie.
|-
|2:13
|So if I were to say - set a cookie that already exists called name, to 'no value' at all.
|-
|2:20
|And use “exp unset” variable to set it to a time in the future, thereby 'unsetting' our cookie.
|-
|2:28
|So I'll get rid of this code for now and run this page, okay?
|-
|2:34
|Nothing has happened presuming my cookie is unset.
|-
|2:40
|Now I want to get rid of this code - so I'll comment this out.
|-
|2:45
|And I'll put my 'if' statement back into my page.
|-
|2:48
|Now presuming this says - is the cookie set name? I'm going to unset the cookie which should get the result "Cookie is not set".
|-
|2:56
|Lets refresh and we got "Cookie is not set".
|-
|3:02
|And then from here you can set it again if you like and you can change the values of the cookie.
|-
|3:08
|To change the value of a cookie, you'll have to use 'setcookie' command again.
|-
|3:13
|You’ll say - set cookie name and here just type a new value
|-
|3:17
|So its not hard to work with cookies.
|-
|3:19
|Its quiet an easy process.
|-
|3:21
|And it’s a very very useful thing in php
|-
|3:23
|So use it to your heart’s content. Okay. Thanks for watching.
|-
|3:27
|If you have any questions, please let me know.
