Re: [PHP] why should $_SESSION be slower than other arrays?
In any case, it would appear the comments in the session section of the online docs are wrong or just out of date, and I don't need to worry about it. I'll go ahead and add a comment to that effect on the ref.session page. l8r Aaron --- Marek Kilimajer [EMAIL PROTECTED] wrote: Chris Dowell wrote: Entirely off the top of my head, I would imagine it has to do with the scope of the variables in question. When assigning a value to a variable, there must be some time spent resolving the scope in which that variable is valid, to see if the new value overwrites any existing value and to ensure that it is accessible from the correct places. As a superglobal, however, $_SESSION has a very specific and unchanging scope. If I were Zeev or Andi, I'd have added a little optimisation into ZE to check for trivial cases such as this and shortcut the tedious scoping. I could be wrong, but this seems to be the most obvious explanation. Has anyone tried this with any other superglobals like $_POST or $_SERVER? Just tried it, $_SESSION is certainly faster then $_POST, $_GET and $_SERVER: Session var: 0.380021095276 GET var: 0.50522685051 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php __ Do you Yahoo!?

[PHP] why should $_SESSION be slower than other arrays?
I read in the docs several comments that $_SESSION is slower that other arrays. One comment even had benchmarking info indicating it was about half as fast. I don't understand why this should be. Isn't $_SESSION just a normal super global array like any other, except that it get serialized and written to disk *once at the end* of a request? Why on earth would this impact the performance of reading and writing in the middle of a request? Is there some funkyness going on under the covers that I'm missing? Can it be made to work as I described? l8r Aaron __ Do you Yahoo!? New and Improved Yahoo!
