PHP Novice on the road (ii)

2. Competitor: asp,mod_perl,jsp





is used to implement interactive dynamic Web pages, where CGI is also known as the Universal Gateway Interface (Common Gateway Interface), which is the standard programming interface between external programs and Web servers, but there are too many drawbacks to CGI programs While Perl solves the problem in CGI and is used to drive complex web technologies, Microsoft's ASP (Active Server Pages) appears to be easy to use, Easy to write programs and strong backing of Microsoft software makes the ASP suddenly become a professional programmer and the darling of the professional programmers; cold fusion of Middle Ware and Allaire is another solution, and cold Fusion has a proven reliable search engine components; JSP is the new generation of web development language launched by Sun and so on. With so many dynamic Web technologies, you might ask: "Why do I have to choose PHP?" ”





before answering this question, let's take a look at the pros and cons of asp,php and JSP.





2.1 About ASP





ASP because of its simple function and practical, such as the broad masses of friends like, coupled with the strong support of MS, can be said to be the most popular language at the moment, he used the MS COM + technology, can almost achieve in C/s can achieve all the functions, it can be said to be quite competitive ASP's code implementation is also very simple, MS provides InterDev on the basis of RAD, so that the development of ASP over the night across the river. But his disadvantage is that, because of MS's long high-handed style, he can only run on the mobile suit platform, so it is difficult to easily accept the key applications.





2.2 about JSP





JSP is the Sun introduced a new generation of site development language, he completely solved the current asp,php a common problem-script-level execution (now PHP4 also has the support of Zend, implementation of the compile run). With its own extraordinary Java attainments, Sun has a new fruit in addition to Java applications and Java applets, the Jsp--java Server Page. JSP can complete the powerful site program with the support of Serverlet and JavaBean.





as far as I know, JSP is based on Java, so Java programmers can easily start coding. ASP is just a generic engine with the ability to support multiple languages, but the default and most commonly used is VBScript. Mod_perl is as powerful as Perl, just a little faster.





for ASP, JSP, PHP and so on, in the end what kind of language is better? Different people have different views. But one thing we have to be clear about is whether you know how expensive it will be to buy them, as well as how expensive and powerful the hardware is, for ASP, JSP, and so on. If you have any neutral points of view (such as not affected by the million dollars of Sun and Microsoft), please let me know.





2.3 About PHP





PHP is the GNU style of Linux, with the help of open source, so that he quickly become the world's most widely used site production language. In the form of C + +, referencing the concept of the class, making the code repeatable application of the exception is simple. Plus he and Linux,apache and MySQL close cooperation, the key application is no problem (famous Sina is the use of PHP). At the same time, the PHP fourth generation Zend (PHP4) The core engine of the official version has also been released, the entire program's core has been greatly improved, so that the PHP program to perform faster. The efficiency of PHP after optimization has been better than traditional CGI or ASP programs. And because PHP is free, anyone can access the PHP Web site and download the full source code. More importantly: the code written in PHP will execute faster, can achieve the same function of the PHP code, without change can be on different Web servers, different operating systems run. With this, you have enough reason to choose PHP.
