php session cookie not gone after closing browser

Book said, persistent cookie stay on client machine till it expires. session cookie will be gone after browser closed.

i tried it, like:

setcookie("name", "value");  // before any output

but after closing browser and restart, it is still there (from print_r($_COOKIE)).

i tried couple of different browsers like safari, chrome, firefox, it is all like that. only eclipse is different:)

so, are all current browsers not following that "rule" ? or there is some default time-out for a session cookie i am not aware of?

thanks.

EDIT:

I checked in firebug it said:

Name Value Domain Expires

name value localhost session

you'd have to check your particular cookie settings. YOUR particular php may be configured to set permanent session cookies. session cookies are supposed to be temporary ones, bu that's purely a convention. nothing says someone can't set permanent session cookies. - Marc B
Can you please add what you observe in the headers of that request network panel of those browsers? - try-catch-finally
To Marc B: thanks. in firebug, it said "session", so that means it is a session cookie. then the problem is when will the "session cookie" expire:) - totally

Check your PHP settings for session cookie name, domain and path, and unset the cookie using the same values given to setcookie(). They can all be read with ini_get() and fed to variables.

The above advice assumes you're using PHP built-in session mechanism, ie. you don't use a framework with it's own, custom session library.

What you set there is not a session cookie. After the page is loaded in the browser go check the cookies set from your server (localhost if it's local machine), you'll see a SESS_ID cookie which is set by the server and it goes when you close the browser

What you are actually trying to set is a persistent cookie..A session cookie or simply session can be simply set by starting a session or storing a value in session like $_SESSION['name']=$value.

What you are doing is a persistent cookie it wont expire even if browser is closed. It expires only after the time set in cookie expires.

Like setcookie($cookie_name, $cookie_value, time() + (86400 * 30), "/"); it will set cookie info for 1 day..even if browser it closed..

You can set time and cookie info according to your needs... `

That's because you're setting a cookie.

Sessions are not cookies. Cookies are not sessions.

Quoted from the first page:

Cookies can be set to a long lifespan, which means that data stored in a cookie can be stored for months if not years.

And sessions, via the page on sessions:

It is also important to note that sessions only last till the user closes their browser, whereas cookies can be configured to last longer.

Thanks to everyone's response. It's my problem. i am working on macbook, i thought clicking the red cross will close the browser. but although browser is gone. on the very top of my screen, it is still safari menu bar. i have to click safari and quit it.

now, all my session cookies are gone after closing the browser:)
