An HTTP cookie (web cookie, browser cookie) is a small piece of data that a server sends to a user’s web browser. Cookies are mainly used for three purposes: Session management. Logins, shopping carts, game scores, or anything else the server should remember.
In the real world: YES. You CAN use PHP sessions without cookies, as long as the browser identity is obtained somehow and yields a unique value (and this value is passed to the PHP session layer):
What are sessions cookies?
A session cookie is a file containing an identifier (a string of letters and numbers) that a website server sends to a browser for temporary use during a limited timeframe. When the browser closes at the end of a session, the file is deleted. A session cookie is also known as transient cookie.
Which is better session or cookie?
Cookies store it directly on the client. Sessions use a cookie as a key of sorts, to associate with the data that is stored on the server side. It is preferred to use sessions because the actual values are hidden from the client, and you control when the data expires and becomes invalid.
How to retrieve the value
- Hit F12 – This should open the developer console.
- In the console window, click the Cache menu and select view cookie information.
- This will open a new page with the cookies listed.
- Find the item with the name PHPSESSID.
- Copy the value next to VALUE – this is your session id.
What is session used for?
Basic usage ¶ Sessions are a simple way to store data for individual users against a unique session ID. This can be used to persist state information between page requests. Session IDs are normally sent to the browser via session cookies and the ID is used to retrieve existing session data.
What is stored in session cookie?
A session cookie is a file containing an identifier (a string of letters and numbers) that a website server sends to a browser for temporary use during a limited timeframe. This type of cookie is stored in temporary memory and is only available during an active browser session.
What does a session?
1 : a meeting or period devoted to a particular activity The football team held a practice session. 2 : a single meeting (as of a court, lawmaking body, or school) 3 : a whole series of meetings Congress was in session for six months.
Here’s how it works:
- Server opens a session (sets a cookie via HTTP header)
- Server sets a session variable.
- Client changes page.
- Client sends all cookies, along with the session ID from step 1.
- Server reads session ID from cookie.
- Server matches session ID from a list in a database (or memory etc).
What is a session in browser?
A session is defined as a series of related browser requests that come from the same client during a certain time period. Session tracking ties together a series of browser requests—think of these requests as pages—that may have some meaning as a whole, such as a shopping cart application.
What is better session or cookie?
Sessions are more secured compared to cookies, as they save data in encrypted form. Cookies are not secure, as data is stored in a text file, and if any unauthorized user gets access to our system, he can temper the data.
Are sessions the same as cookies?
Cookies are client-side files that contain user information, whereas Sessions are server-side files that contain user information. Cookie is not dependent on session, but Session is dependent on Cookie. Cookie expires depending on the lifetime you set for it, while a Session ends when a user closes his/her browser.

Websites typically use session cookies to ensure that you are recognised when you move from page to page within one site and that any information you have entered is remembered. For example, if an e-commerce site did not use session cookies then items placed in a shopping basket would disappear by the time you reach the checkout.
What is the difference between browser cache and sessions?
Session data is stored at the user level but caching data is stored at the application level and shared by all the users.
