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 :) -- Lester Caine - G8HFL - Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Question about performance between for iteration and extension function
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. -- Best Regards, Yo-An Lin

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. -- André Majorel http://www.teaser.fr/~amajorel/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

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.

[PHP] PHP, PDO and MS-SQL ?
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? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
