Re: [PHP] please help with regular expression in preg_replace
Many thanx to Jim and andy for their replies, with Jim`s changes its now working like in sed. Excuse me for my stupid question, but im old unix/linux system engineer coding with C , perl and bash, php gave me unpredictable results in this task. ;-) so, in final, may be this help some other roundcube users who need one universal site for many domain access. this is test page: ?php $host = host.1stdom.com ; //$host = host.2nddom.1stdom.com ; $pattern1 = '/[^.]*\./U' ; $pattern2 = '/^[^.]+\./' ; exec( echo $host | sed s/[^.]*\.//, $dom_sed ) ; $p1_1 = preg_replace( '/[^.]*\./U' , '', $host ) ; $p1_2 = preg_replace( $pattern1 , '', $host ) ; $p2_1 = preg_replace( '/^[^.]+\./' , '', $host ) ; $p2_2 = preg_replace( $pattern2 , '', $host ) ; echo $host br ; echo dom_sed = $dom_sed[0]br ; echo p1_1 = $p1_1 br ; echo p1_2 = $p1_2 br ; echo p2_1 = $p2_1 br ; echo p2_2 = $p2_2 br ; ? with result: host.1stdom.com dom_sed = 1stdom.com p1_1 = com p1_2 = com p2_1 = 1stdom.com p2_2 = 1stdom.com and this is line which i need in roundcube setup: $rcmail_config['username_domain'] = preg_replace( '/^[^.]+\./' , '', $_SERVER['HTTP_HOST'] ) ; many thanks again Rene - Original Message - From: Jim Lucas li...@cmsws.com To: Red r...@you.sk Cc: php-general@lists.php.net Sent: Friday, October 30, 2009 12:33 AM Subject: Re: [PHP] please help with regular expression in preg_replace Red wrote: hello, im not a php developer, i just need to rewrite one php file but having problem with understanding syntax of regexp in php. i need to get domain name from fqdn (for example from $_SERVER['HTTP_HOST'] ) in sed its working well with s/[^.]*\.// , but preg_replace behaves weird. http_host is for example hostname.domain.com ?php $host = $_SERVER['HTTP_HOST']; exec( echo $host | sed s/[^.]*\.//, $domain ) ; echo $domain[0] ? return domain.com, but ?php $host = $_SERVER['HTTP_HOST']; $domain = preg_replace( '/[^.]*\./' , '', $host) ; echo $domain; ? return only com i think when this php page get many hits, its not so wise to call sed everytime, i would like to ask someone for help how to write preg_replace pattern. thanx Rene I would add one thing and change another. ?php $host = $_SERVER['HTTP_HOST']; $domain = preg_replace( '/^[^.]+\./' , '', $host) ; echo $domain; ?

RE: [PHP] dynamic menu with show hide capabilities - understanding possible workflow
-Original Message- From: MEM [mailto:tal...@gmail.com] Sent: terça-feira, 27 de Outubro de 2009 12:05 To: 'a...@ashleysheridan.co.uk' Cc: 'Jim Lucas'; 'php-general@lists.php.net' Subject: RE: [PHP] dynamic menu with show hide capabilities - understanding possible workflow Think of it a bit like an online shop selling operating systems: 1) All the main OS's you sell are on the front page - Linux, MacOS Windows 2) User clicks on Linux, and is taken to the url /products/linux and they are shown all the Linux OS's on offer (Fedora, SuSe, Ubuntu, Knoppix, etc) 3) User clicks on Fedora and is taken to the URL /products/linux/fedora and they are shown all the versions of Fedora up to 11 4) etc The URL belies what section you are on, which makes it easy for the user to remember, and easy for you to extract information from to know exactly where the user is. Obviously in the above URLs I'm assuming mod_rewrite is being used. Thanks, Ash http://www.ashleysheridan.co.uk Thanks a lot! Really. I will now start coding based on all this information and see what I will get. I'm sure that the designer will kill me later, by telling me... couldn't we just... fade in this a little bit... Ahhrrggg!!! Regards, Márcio Hello once again, I have take my time to think on this for a while. And I end up on the W3C recommendations about URIs: In a phrase: Keep it semantic, lifetime, and short. Several questions arise at this moment: I was having a url like this: http://www.mysite.com/c_mycontroller/method/1/3/4/54 Where the numbers where Id's of categories or products. Well... this could be as far as we can get from the W3C recommendations. :s So, let's say I short those urls to names, and I remove/hide(?) from the URL the controller and method information's. We could end up on something like this: http://www.mysite.com/categoryname/subcategoryname/subsubcategoryname/productname/ It's more semantic. But what if we have, 4 subcategories for example? This could get quite long. A possible solution to this, is to have something like this: http://www.mysite.com/categoryname/subcategoryname/productname In a way that we always get no more than 3 URI segments. So, if the user navigates to a sub sub sub sub level on the hierarchy, the address could be: http://www.mysite.com/categoryname/subsubsubsubcategoryname/productname 1) What are your thoughts on this? Should I follow this track on your opinions? 2) In order to be semantic, I intend to pass through the URI segments, NOT the Category id's but the Category names. This will bring two issues (at least): 2.1) - I need to query the database, not by ID but by Name. (I'm not sure if they always be unique, I'm not sure if I will have a performance issue). As a note: This is a VERY little website. Nothing too fancy. 2.2) I will grab the categories name from the database, and build the URL with those names, however, some category names will have INVALID chars, like á, ç, spaces... etc... What would be the best way of doing this? Having a new column on the database categories table with a slug field? Or, grab the category name, and prepare that name to be url friendy using a function for that? If it's possible to answer, where on a MVC structure would this function be?

[PHP] How APC Work?
Hi, How *APC* – Alternative *PHP* Cache store data on cache? memory? file system? i´m developing a PHP application with many requests for read/write on APC stored variables, im scared with future slow down with many IO on APC. Thanks, Erick Couto
[PHP] smtp mail question
Anyone see a problem if I login into the smtp server with Username different than the Return-Path? It seems to work OK; but, I know from experience using the mail servers that increasingly everything must be exactly right to prevent recipient mail servers from rejecting emails. So, I started using authenticated smtp exclusively. Reason I'm asking is that I'm developing an application that will have several pages and each one will have a different Return-Path and Reply-To. It will make things simpler if I can login to the smtp server with just one username/password.

It seems to work OK; but, I know from experience using the mail servers that increasingly everything must be exactly right to prevent recipient mail servers from rejecting emails. All the email servers I have worked with only care about the proper authentication credentials and accept any valid email address for From: Reply-to and so on. Free services, like Googlemail.com, may differ. The receiving server on the other hand will usually do a domain validation of the From: field to ensure that the domain exists, validate the SPF record and do a few other anti spam tricks. -- John -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
