PHP and MySQL

As of 3.2, you’ll need to be running PHP 5.2.4 and MySQL 5.0. As we mentioned almost a year ago when we announced that this change was coming, the percentage of people running older versions of PHP and MySQL is relatively low. With more than 45 million people using WordPress, though, even a small percentage can mean a lot of people! Don’t caught with your pants dashboard down — make sure you’re running compatible versions of PHP and MySQL before you update tomorrow when WordPress 3.2 is released.

Log in to your hosting account, and check to make sure you have at least  PHP 5.2.4 and MySQL 5.0. Most of the major hosts already default to these or newer versions, but there are some exceptions. Check to see which versions you are running, and if you’re still on an older version, it should be as simple as changing a dropdown menu and clicking Save to get up to date.

If you don’t know how to find this information in your hosting account or you don’t even know how to access your hosting control panel because someone else manages that for you, don’t fret. You can find out if you’re ready for 3.2 with the Health Check plugin. In your dashboard, go to Plugins → Add New and search for “health check” (it should be the first result). Install it, activate it, and it will tell you if you need to update anything.

If you need more help, contact your host’s customer service and use this email template to ask them to help you.

Hi there. I host my domain [example.com] with you, and I run WordPress on my site. The minimum requirements are changing to PHP 5.2.4 and MySQL 5.0, and I would appreciate your help in confirming that my site’s setup meets these requirements. If I’m currently running an older version of PHP or MySQL, could you update it for me, or tell me how to do it? Thanks so much!

If your host replies that they can’t update to these versions, it might be time to look for a new host.

IE6 and Outdated Browsers

With 3.2, we’re also dropping support for Internet Explorer 6, a 10-years-old outdated browser that even Microsoft is ready to leave behind. From now on, if you access your WordPress dashboard from an outdated browser, we’ll let you know. Why? Because as web technology improves, so does WordPress, as we build features to take advantage of these improvements. If you’re using an out-of-date browser, chances are you’re missing out.

If your browser is out of date, you’ll see a friendly orangey-yellow box in your dashboard letting you know you a newer version is available (which you can dismiss, of course). If you’re using IE6, though, the box will be red, and your dashboard will not function properly. If you’re stuck on IE6 because the computer you use is maintained by a business, library, school, or the like, and you are not able to download a newer browser, here’s a sample email you can use to ask your boss/administrator/IT guys to update the browser.

Hi there. The computer I use at [where you use the computer] is equipped with an out-of-date web browser. Internet Explorer 6 was created 10 years ago, before modern web standards, and does not support modern web applications. More and more sites and applications are dropping support for IE6, including the new version of WordPress. Even Microsoft, the makers of IE6, are counting down until IE6 goes the way of the dinosaur (see http://www.ie6countdown.com/ for more information). Can you please install an updated version of IE or any modern browser (see http://browsehappy.com for more information) on the available computers? Thank you very much.

Welcome to the future!

First up, the announcement that developers really care about. WordPress 3.1, due in late 2010, will be the last version of WordPress to support PHP 4.

For WordPress 3.2, due in the first half of 2011, we will be raising the minimum required PHP version to 5.2. Why 5.2? Because that’s what the vast majority of WordPress users are using, and it offers substantial improvements over earlier PHP 5 releases. It is also the minimum PHP version that the Drupal and Joomla projects will be supporting in their next versions, both due out this year.

The numbers are now, finally, strongly in favor of this move. Only around 11 percent of WordPress installs are running on a PHP version below 5.2. Many of them are on hosts who support PHP 5.2 — users merely need to change a setting in their hosting control panel to activate it. We believe that percentage will only go down over the rest of the year as hosting providers realize that to support the newest versions of WordPress (or Drupal, or Joomla), they’re going to have to pull the trigger.

In less exciting news, we are also going to be dropping support for MySQL 4 after WordPress 3.1. Fewer than 6 percent of WordPress users are running MySQL 4. The new required MySQL version for WordPress 3.2 will be 5.0.15.

WordPress users will not be able to upgrade to WordPress 3.2 if their hosting environment does not meet these requirements (the built-in updater will prevent it). In order to determine which versions your host provides, we’ve created the Health Check plugin. You can download it manually, or use this handy plugin installation tool I whipped up. Right now, Health Check will only tell you if you’re ready for WordPress 3.2. In a future release it will provide all sorts of useful information about your server and your WordPress install, so hang on to it!

In summary: WordPress 3.1, due in late 2010, will be the last version of WordPress to support PHP 4 and MySQL 4. WordPress 3.2, due in the first half of 2011, will require PHP 5.2 or higher, and MySQL 5.0.15 or higher. Install the Health Check plugin to see if you’re ready!

When we started, Yahoo asked “What would the perfect blog host do?” and their team has been really amazing in executing on a really kick-ass platform for serious bloggers. It took a little while, but slow cooking makes good eating. (Like WordPress 2.0!)

We think the hosting is good for all the baseline features you should expect — tons of storage, bandwidth, Yahoo reliability, etc. (You probably heard all about that in their Movable Type announcement last week.) However we think they’re worth featuring because of three key things:

• With just a few clicks, Yahoo Web Hosting will install WordPress 2.0 complete with a few choice plugins and themes. Setup one blog or two dozen in seconds.
• They will also upgrade your WordPress when a new stable release or update is available, meaning it is a zero-maintenance solution on par with WordPress.com.
• Finally, every Yahoo Hosting customer gets a free Pro-Blogger Akismet license ($5/mo value) and Akismet is auto-enabled on new installations, meaning that spam is less of an issue on Yahoo WordPress blogs. (Much like their stellar email spam handling.) Read more about this.

Guy Yalif from Yahoo says, “We believe that by adding WordPress’blogging application to our leading web hosting product, we are providing a top notch, scalable, and reliable solution for less than $12 per month.”

We think the above makes a very compelling case for WordPress users to check out Yahoo hosting, and see what we believe is the best WordPress hosting experience on the Web. As always, if you have any feedback on Yahoo or any other host we feature, please let us know.
