As a reminder to all of those out there wanting to attend this year's PHP Community Conference - it's only two weeks until the event, so you better register soon!

The PHP Community Conference is a two-day event. We kick things off with a tutorial day that will introduce you to tools and ideas that you can use in your code right away. The second day will consist of presentations that will inspire you to create something new with PHP.

The conference is happening April 21st and 22nd in Nashville, TN and tickets for the two-day event are $300 USD. There'll even be a Pecha Kucha event where two iPad2s will be given away. You can find out more about the schedule and the rest of the conference on the event's website.

On Qafoo.com there's a new tool that's been introduced to help you keep track of the current Call for Papers that are currently happening for PHP conferences. The start of the PHP conference season is in full swing, and sometimes it can be hard to keep up. Their Call for Papers Manager can keep that information at your fingertips.

The tool works quite simple: You can add CFPs you know about and which are relevant for the PHP community through a simple form. In order to remember the CFPs, you can configure two kinds of reminders: fFor upcoming CFPs and for ending CFPs. For each of these lists, you can determine when to be reminded, like 2 days before the event occurs. These lists can then be easily integrated into your normal feed reader using an RSS or Atom feed.

You can use the URL requested to get different kinds of reminders delivered to your feed reader too. If you have a conference and your Call for Papers is open or upcoming, add it to the list!

The PHPBenelux 2011 conference's Call for Proposals has been open since earlier this year but the deadline for submission is on the horizon.

After a successful first conference earlier this year, the PHPBenelux team is proud to announce the 2nd edition of the PHPBenelux Conference. We're extending to two days this year with a half day tutorial, and 1.5 days of conference. The conference is on Friday 28th January and Saturday 29th January in Antwerp. Become part of this year's speaker schedule at the PHPBenelux Conference 2011. Each chosen speaker receives a speaker package!

Talks should be about 60 minutes including Q&A and can be on a wide range of topics (some of their suggestions include content management systems, frameworks, best practices, etc). But remember, you need to submit your proposal before the end of the month to be considered!

Andi Gutmans has posted a reminder about the upcoming Zend/PHP Conference and Expo happening Spetember 15th through 18th in Santa Clara, CA.

I can't believe it's already ZendCon time again! I've been meeting with the planning committee and I'm really excited about this year's conference. All the usual things are back to make it great: we have a great lineup of speakers, the Meet the Teams session, and special guests like noted PHP security expert Stefan Esser, Dion Almaer and Ben Galbraith of ajaxian.com, and Alex Russell from Dojo.

He mentions things like the unconference (with even more great speakers, just in a more "unofficial" setting) and about the conference wiki with more details on who will be there and what they'll be attending.

There's still seats open for this year's conference, so reserve your spot today - check out the registration page on the ZendCon site for more information.

Those PHP developers that live around the Columbia, MD area might want to drop in to the PHP user group meeting that Theo Schlossnagle mentions on his blog today:

Just a friendly reminder that we'll be having our first meetup [on 05.14.2008] as planned. I thought as a good kick-off we could all collaboratively share what we do with PostgreSQL. We'll start off with a whirlwind tour of how OmniTI uses PotsgreSQL, taking a brief look at ZFS, DTrace and large datasets.

The event will be happening here and will start at about 6:30pm.

The coordinators for this year's DC PHP Conference have submitted a reminder for developers out there looking to attend:

To get the full details or to just sign up right away, head over to the main conference site and get all the details. Pricing starts at $695 USD ($400 for students) and includes two days jam packed with PHP goodness.

DevShed has posted the last part in their look at the creation of an invoicing system to help you manage your clients today. This time, they focus on the management of users of the system (not the clients to invoice, that was this part).

In this fourth and final article covering the creation of a PHP invoicing system, we're going to put together the user management section. In this section we will be able to view all available users and do all the associated things like deleting or updating user details. We are also going to be able to add new users.

They start with grabbing the information of the current users of the system and listing them out. This allows simple modification and deletion of any of the users on the list. They give the code (and screenshots) for the user modification screen and show you how to set up an email reminder that sends out to the clients when a bill hasn't been paid.

Ben Ramsey has posted this reminder for all of those wishing to attend the upcoming PHP Appalachia conference about signing up.

PHP Appalachia is an informal gathering of PHP enthusiasts who just want an excuse to get together and enjoy exchanging information in a relaxed, beautiful setting. There is no set agenda, no formal speakers. Just 3 days of camping and sharing PHP ideas and experiences with people just like you.

The event takes place September 27-29, 2006 at the Cherokee/Great Smokies KOA in Cherokee, NC. To receive the group discount for your camping site/cabin, you must reserve your spot with the campground before July 5! See the PHP Appalachia Web site for more details.

He also mentions two other things:

• a post on the conference site asking those coming to the conference for "topics of interest" they'd like to hear about
• a brief "rant" from Ben with a "chicken and egg" scenario - problems getting sponsors because of current signup numbers, and problems getting signups because of the lack of sponsors (and what they can pay for to make it free for attendees).

The Atlanta PHP Users Group has posted a reminder about their February meeting happening tonight, the 2nd at 7pm in Tucker, Georgia.

Our February meeting will start with a new short session of PHP Tips & Tricks. This will become a regular tradition at our meetings, and we hope it encourages and helps newcomers and seasoned PHP programmers alike. See Chris's reminder to bring your Tips & Tricks: http://www.atlphp.org/node/120

Following the Tips & Tricks session, we will dive into another new segment that will surface from time-to-time at meetings throughout the year: PHP Topics. PHP Topics will be a programmer-to-programmer open discussion forum about some topic related to the PHP community. We'll do this on a semi-regular basis (i.e. once a quarter). If it turns out to be a popular segment, we may set aside some time for a short discussion at each meeting.

You can get the full details for the meeting here including directions to the meeting place.
