PHPVSASP_PHP Tutorial

Microsoft's ASP is a powerful dynamic WEB page technology. I have been using ASP for a year and used it to create many WEB sites, but now my company is thinking about switching to another INTERNET technology called PHP for development. Future WEB site development. The problem is that we are accustomed to using ASP and like using it, so why should we switch to PHP? Open Source Movement First of all, we realize that the open source movement has given us strong technical support and free code supply. For example: in ASP, uploading files, encrypting passwords, and sending emails all require the support of third-party commercial software and are charged; but in PHP, all of this is free! But that wasn't enough to convince us to switch to PHP because we already invested a lot of time and money in these necessary business software tools. INTERNET Programs and LINUX I have a dream. I hope that in the future every program will be an INTERNET program. There is no need to buy software packages or install them. They are available on the Internet and are already installed. We only need to run the program in the browser, which does not require too much configuration. Most web applications run on LINUX and PHP. They usually do not use ASP. There is a software called Chilisoft ASP, which can run ASP on LINUX, but it costs money. At the same time, it does not support the latest version of ASP. More importantly, it is good for creating high-performance ASP sites. None of the third-party DLLs can run on LINUX. So, in order to realize our INTERNET software dream, we decided to find a better technology that is close to ASP to replace it! ISAPI support The PHP core engine being developed by the ZEND team includes an ISAPI engine. ISAPI is a MICROSOFT INTERNET WEBSERVER API. Its application gives us programmers who are accustomed to developing programs under WINDOWS a shortcut to LINUX. Technical Analysis Everyone claims that their product is the fastest, that's not what I really care about --- I only care about "fast enough", and for me, PHP is fast enough! ASP supports multiple programming languages. This system makes the program inherently slow and takes up a lot of memory. Each language parsing is equivalent to a PHP compilation (that is, when ASP starts to parse a code, it is equivalent to starting multiple PHPs at the same time) , when ASP parses an ASP start tag (
