php session expiry

[harintfs]

Dear
I would like to set session expire time to 3hrs,
Which one is best ?
ini_set("session.cookie_lifetime","10800"); or session_set_cookie_params(3600 * 3);
Or can I use both?
Is it compulsary to place every page b4 where ever session_start();
And one more above said syntax is correct or not? because some people using "10800" and some '10800' others just 10800. how to set?

Thanks. Pls help me

both of them will do the same trick

but 10800 is better than 3600*3, php wont have to parse unnecessary equation. And yes you can use whichever you want.

Yes it is compulsory. in simple when you do session_start it creates all the necessary data list for you page purpose.

"10800" , '10800' and 10800

all of them are correct. it may have performance issue, i am not sure about it though.

but in some cases they will show difference

such as
("10800"==10800) will return 1 i.e. true

("10800"===10800) will return false

cause in the second comparison first data is treated as string and the second data is treated as number.

Dear Friend,
I used session_set_cookie_params(10800); But now I am facing some problem. After 1 hr (on 65th min)even with activity (frequent clicks on page) at the time of submitting my page its expires, What may be problem? How to fix it?. I tried to work 45 min with activity and submit there is no expiry problem.
I am using shared hosting.

here is a suggestion from php.net site

Set cookie parameters defined in the php.ini file. The effect of this function only lasts for the duration of the script. Thus, you need to call session_set_cookie_params() for every request and before session_start() is called.

Yes, I using session_set_cookie_params(10800); before calling session_start .. each page. Wheter I need edit php.ini? And also I am attaching my current php.ini config file.
Thanks
