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 (

PHP's Purpose: Building Dynamic WebsitesApr 15, 2025 am 12:18 AM

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP: Handling Databases and Server-Side LogicApr 15, 2025 am 12:15 AM

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

How do you prevent SQL Injection in PHP? (Prepared statements, PDO)Apr 15, 2025 am 12:15 AM

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python: Code Examples and ComparisonApr 15, 2025 am 12:07 AM

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP in Action: Real-World Examples and ApplicationsApr 14, 2025 am 12:19 AM

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security.
