This is fixed in PHP 5.4 by completely dropping support for the TZ
environment variable. PHP will always use UTC unless you explicitly set
it to something. It won't matter which timezone the system is running
in. This is the only reliable way to always have consistent behaviour
across all environments.
Just taking that a step further ...
The second that you need to actually take a users time zone into consideration,
then the best way of working is to RUN the sever set to UTC. And store any time
information in UTC. Then you can display times TO USERS either as UTC, or as
their own local time or the local time of the location an event is happening at.
You just need to remember that timezone information provided by the browser is
only todays time offset, so any area with daylight saving will be wrong for half
of the year, so that is the point you need to store a user or loction timezone
reference. Many systems still only store 'offset' which is simply wrong :)

Hi folks,
I am in doubt of this, I thought pure php iteration is slower than calling
join or other extension functions.
but the result shows: https://gist.github.com/b2a94c94ca66a55814d4
Using Pure PHP for iteration is faster than using join function. why ?
because of the php runtime typecasting ?
And json_encode is the most slowest.

There's a bug in your first test (the php iteration). You're using $i
for the inner and outer loop, meaning that the outer loop will only
run once. Try this updated example:
https://gist.github.com/1452696
On my box it gives(with microtime instead of your timer class):
php join.php
n=1000
Pure PHP iteration: 0.87661409378052
String join: 0.13562703132629
json_encode: 0.081185102462769
json_encode is the fastest one here.

Thank you. That's too much code for the amount of time I had,
though. So I just added the purging of old records to the code
that creates them.
It's not ideal in that old records remain until someone opens a
new session. But it's quicker and safer than writing a whole
session handler.

Hi,
could someone tell me what I need to install and how to configure
everything so that I can connect with PHP and PDO to a MS-SQL server?
I have an OpenSuse 11.4 installation. I added the Apache-PHP repository
and upgraded to PHP 5.3.8.
php-mssql, -php-odbc, libfreetds and the freetds-tools are installed.
Do I need all this or anything else?
phpinfos() reports the odbc and mssql modules are loaded.
I can't find config files, though.
The aim is to connect to a ms-sql server using PDO without a system dsn
if possible.
Is there a detailed description for people who don't know everything
about this stuff, yet?
