I have been writing a lot test cases for a large web project built by symfony. From time to time I found the build-in testers are not sufficient to test my application thorough enough. Often times it is not possible to simulate the way a user would interact with the application. For this reason, I have turned to Selenium.
Though it takes some extra work to get it to work with symfony's Lime test framework, the result turns out to be very satisfactory. The following is for those who are interested at the integration process. All code examples shown here are written using a Linux box, but they should also work under Window environment.
This is not yet another regular expression replacement template engine. The template engine uses PHP itself to render the template. The template itself is very intuitive to people who are already familiar with PHP. There is no extra learning for additional syntax - the template code itself is just plain PHP code. Though I haven't done any benchmark, from my past experience of using it, it is pretty fast - consider that it consists of less than 100 lines of code. Thinking of using Smarty?
In Ajax programming development, passing data back and forth between client and server is a common task. There are two major data formats that one can use for this purpose, namely XML and JSON. My personal preference is JSON because I find it's less verbose and easier to parse.
Although latest PHP provides a very handy function (json_encode) for outputting data in JSON format, for almost every Ajax request I handle on the server side, I have to routinely format the data in a certain way so I can use it conveniently on the client side. For example, to indicate whether it is a valid Ajax request, I embed an field called has_error in every response. I find it's getting annoying after a while, so I wrote a class to automate things a bit.
Update(2009-09-19): JSON encoding and decoding is built into PHP since PHP 5.20. You don't need Zend's JSON support if your PHP version is >= 5.20. Please see:
So you are writing a piece of PHP code to handle some Ajax request and you've just finished coding the business logic. It is time to output some server response so that the page which initiated the Ajax request can obtain the requested result.
You decided to use JSON because you don't want to get your hands dirty by traversing nodes after nodes. After encoding a fairly complex and nested PHP array into JSON, you find out writing such code is very unpleasant and you start wondering if there is an easier way to do this. The answer is yes - Zend Framework will save your day.
