Page counter

[tdipster]

Hi,
I've seen several php scripts to implement a page counter and
they all read a file, update the counter and write the new
counter to the file, for every request ?!?

Isn't there something like having a php script which keeps
track of the counter variable 'in-memory', a bit like a java
servlet which is loaded just one single time and where you
can use context (application scope) variables ?

Is a PHP script loaded (and initialized) for every request or
just once ?

Another question, what about the threading model ? Is PHP
multi or single threaded ?

Greetings,

this must be done for every request, cause there's nothing running all the time,
a script is called by request

usually the script is loaded each time (afaik), but there may be
caching methods (dunno)

threads: my limited knowledge tells that there exist several Apache
child processes, from which everyone could call PHP, I guess
