ZDE does not seem to have changed on the surface. :) The overall style is almost unchanged. but it is obvious that the speed is much faster. as always, only Chinese fonts such as can be used for Chinese display. It is unclear why Zend has been improved. the new features of ZEND are as follows: 1. profier ...... This is too strong ......... It's really strong. it seems that the DEMO is too strong. Unfortunately, I didn't have Performance suit, but it seems that I have to install it to use this function. 2. code Analyzer Code analysis is very cool. You can see it. it makes your application more secure. the analysis documents are all very cool experiences. 3. the Debug button on the browser. you need to install Zend Server. 4. supports PHP5, especially some new syntax Keywords of PHP5. enhanced code filling function. you can see. then you will get automatic comments before the function. it is convenient for you to modify. in addition, the information for ZDE auto-filling is provided by annotations. this is a feature that helps you develop good habits. at the same time, the auto-Fill function is indeed enhanced. If you are used to Visual Studio and so on, this is indeed a good function. it can also be filled with contained files, although sometimes it is not very clever. at the same time, you can click go to source to locate the function directly across files. 6. only HTML and J The syntax of the ava script is highlighted. 7. ZDE is more efficient and faster. Indeed, although it is written in JAVA, It is very refined. ZDE removed from JRE is only 4 MB. in addition, the Code sorting function is available. You can see that the results are very good. it is also very useful, because you may want to take over other people's projects, and the code of that project may be very poorly written... Then this function will show itself. A good development tool is one of the prerequisites for a successful language. At this point, MS has been doing very well. as far as I am concerned, the dislike for PHP still exists, and I have long decided to give up unless I need it. However, ZEND is indeed a surprise this time. I have always been skeptical about the new features promoted by PHP5, but this test on ZDE's support for PHP5 keywords seems to be true. so I am going to contact the current PHP5 BETA version ^_^. I hope it will surprise me too :)
