So today I was able to successfully send an encrypted email from a PHP application of mine. This isn’t too hard to do with basic plain emails and using say GPG with the PHP GPG extension. I played with this first but came to choose S/MIME based encryption method instead since it’s actually supported by nearly every email client without plugins/addons. This seems way more ideal, you can even get a free certificate from thawte for email use. I was able to find out how to do this in PHP via the openssl extension’s openssl_pkcs7_encrypt function. So today I finished up the encryption support in the web application I was working on by getting html emails to encrypt & send and then show up right on the other end. Was pretty excited to get that working, was just a matter of putting the mime/html related headers into the message data to be encrypted.

Small annoying part is the openssl_pkcs7_encrypt function takes file paths for arguments, not variables with data. So you have to save stuff to say /tmp then delete. Kinda stinks.

I’m starting to wonder what the future of Zend Studio is due to disappointing updates and the new PHP IDE Project backed by Zend. I’m quite disappointed that the java based cross-platform application that is Zend Studio isn’t a native application to OS X Intel. Supposedly this should work through rosetta, but come on, it’s java, it shouldn’t have to be specific to PowerPC, and shouldn’t be hard to fix this at least for the primary program. I believe my first attempt to actually install Zend Studio on my MacBook Pro was met in similar failure to the friend that warned me that it has issues on OS X intel. I seemed to have installed 5.5 beta just fine and it so far seems fine. But it’s still severly limited since you can’t use the Zend Debugger, Profiler, or Platform features since that requires the Zend extensions which are PowerPC and you can run PowerPC applications but not load shared libraries like those into intel applications. So basically it’s not a 100% package on OS X intel.

The other issue is that I have an expired Zend Studio 5.1, meaning it’s still valid to use but no free updates, so $200 to get 5.2 or 5.5 when it’s out. And for what? Nothing special at all, there’s some cool stuff, like Zend Platform integration is actually something nicer in 5.5 compared to the initial stuff in 5.2. I’m not sure I like the subscription style upgrade program, it benefits you at times like when a huge release comes out like say if 6.0 was coming out when you still had the support/updates. Mine happened to expire before 5.2 or 5.5 so neither are free, I definitely said no to paying to renew and get 5.2 since there was barely anything at all new, and 5.5 isn’t much better either. Not worth it until maybe 6.0.

Also, is Zend Studio going to be continued or is the PHP IDE Project slated to eventually be Zend/PHP’s preferred IDE of choice. Doesn’t seem like it, but the fact that Zend is helping with what would be competition for Zend Studio seems kinda odd. That and the lack of intel support for Zend Studio and Zend Platform makes it kinda uncertain if it’s worth spending money for an upgrade, at least not until there’s a better looking update that provides something more worthwhile. In the meantime I’m seriously looking at Komodo Professional to see if it’s at all a better deal, specially with all the languages it’s capable of handling, including code suggestion for more than just PHP, but for other languages and also CSS and XSL too. The biggest concerns for that IDE so far are performance/snapiness and limited PHP code suggestion. I don’t know if PHP IDE Eclipse project will be good, at least not yet, but Eclipse has been incredibly slow on linux and OS X. We’ll see how things progress with it.

So with the recent arrival of a MacBook Pro for work, I needed to setup my PHP development environment which usually consisted of Zend Studio, but that has YET to come out with a intel/universal release despite the fact that it’s 99% java. One of the useful things with Zend Studio is that you can debug and profile PHP sites with it, which I don’t actually use all that often, it’s still incredibly valuable. So Zend Studio may actually run fine on here through Rosetta, but word is, not very well and installer has major issues specially with latest version. What will not work at all is Zend Platform or Zend Studio Server, comprising of ZendOptimizer and what not, PHP extensions, which will not load into apache/php at all being PPC library files.

In comes Xdebug, an open source PHP debugging and profiling extension. It also totes a few nice features beyond that, like ability to give you stack traces for just about any error message, including notices and warnings. Installation of Xdebug was easy if you’re familiar with PHP extension compliation, plus if you’re trying out Komodo Pro also, it can install the extension for you and set it up. Xdebug is not too useful by itself, it’s best used with an IDE like Eclipse PHP IDE or Komodo, which allows you to view the PHP source file and step through it, set breakpoints, and see what variables contain what. This pretty much compares on-part with Zend Studio’s debugging abilities, with the added bonus of some other cool features.

The one thing I’d love to see be easier and as nice as in Zend Studio is the profiling of PHP code in Xdebug. This can be enabled and you can flag a page for profiling easily, what this does though is dump a file to a determined folder by the php.ini. This file is a cachegrind format file which can be viewed nicely in apps like KCacheGrind or WinCacheGrind. This would be cool and all if I weren’t on OS X. It doesn’t seem there’s any tool to view this data easily and nicely (specially as nice as a pie graph and such in Zend Studio) in OS X. This seems to be mostly due to the fact that these tools are all based around a tool called valgrind which is for linux and does not run on OS X that I can tell. What I did find after googling a bit is a perl script that will let me get some basic stats out of these files, ct_annotate.pl from the callgrind package. I found this after searching a bit on a mailing list as an attachment. My blog refuses to provide this file though.

I still haven’t had too much experience with Xdebug yet, but I’m impressed so far, just wishing for a visualization tool for cachegrind formatted data in OS X. I also tried Komodo Pro during this whole process, which seems like quite the powerful IDE. I was sparked to try this while looking into Xdebug, and not having any interesting in Eclipse, and running across someone in a similar boat over at Random Strings. This person, also a certified Zend Engineer, used to use Zend Studio but made the switch to Komodo Pro after purchasing a MacBook Pro. Seemed to be pretty positive, at least about debugging. My initial experience is pretty positive, seems to be quite powerful, the newest upcoming release has some nice features like CSS auto-complete, a HTTP inspector, and also ability to debug javascript via Firefox and an extension. I’m still going to give it a run through with my trial copy to get a good feel for it. My biggest problem so far is just that Zend Studio has an incredible auto-completion ability with it’s parsing of PHPdoc tags and being able to complete instance functions etc. Komodo Pro seems to be limited to class names and functions. I’ll probably use Zend Studio again on the MacBook Pro soon as it’s universal or available for intel, which Komodo Pro did very fast.

So you want to setup a Subversion(SVN) repository? Well I know the basics and hopefully I can give a nice to-the-point tutorial on how to get up and running with tracking your source code through SVN. Subversion can easily be used as a personal change tracking system on your local computer, or be used with a team to track changes from everybody and facilititate conflict resolution with similar changes. I also see it as a super undo in case you really manage to screw stuff up. Although proper version tracking requires you getting in the habbit of reguarly commiting changes. Read more for the tutorial (Decided to stop doing full posts on front page, getting LONG)

Update: If your using OS X, check out SvnX for a GUI for manging working copies, and doing some repository actions too.
