session variables

Hi..

Some common functions from global_function.php are called by other php pages but return values are the same.

option 1 :Calling same function for same result from different pages

option 2 : function is called once,return values are set in session variables and they are reused by other pages

If option 1 is used, number of session variables will be 3.
If option 2 is used, number of session variables will be 7.

Calling fun many times is much better than using many session variables ??? Whice one is the fastest and safest to access ldap server ??

we cant tell you the answer based on the info you provided.

it depends what the functions do, how long they take to do it, and how much data they return.

you can always time it yourself. take a look at microtime() to see examples of how to time various parts of a script.

Thank you so much for your information. I think function calls are better than session variables according to the type of (my) system.

regards,
Mitchell
