5_3_x_nts_comp版本的ZendDebugger在PHP5.3(Thread Safety)上安装不成功的原因(转)
自从用上了PHP5.3,问题还真是多,自上次出现连接MS SQL Server的问题后,这次在安装 Zend Debugger时又出现了问题。按照Zend官方给出的Zend Debugger安装步骤,从?这里?下载了最新的 5.2版本的Studio Web Debugger,从解压出的ZendDebugger-v5.2-cygwin_nt-i386\5_3_x_nts_comp目录中复制ZendDebugger.dll 到PHP安装文件夹下的ext目录,然后编辑php.ini文件,在文件最后加入一下三行: zend_extension = "d:/php/ext/ZendDebugger.dll" 然后把dummy.php文件复制到apached的 "DocumentRoot"目录(在http.conf文件中设定),可重启Apache服务后 用phpinfo()显示的页面中并没有Zend Debugger,很明显,安装没有成功。 回过头再仔细看Zend的安装步骤介绍,发现zend_extension这项配置有两种,除了zend_extension以外,还有设置为zend_extension_ts的,分别适用于Non-Thread-Safe和Thread-Safe版的PHP,而我安装的PHP是Thread-Safe版的(通过phpinfo() 页面的Thread Safety选项可以查看到),所以应该用zend_extension_ts,但是我下载的Studio Web Debugger 针对php 5.3版的只有nts版的ZendDebugger.dll (从文件夹名称可以看出-5_3_x_nts_comp). 仔细搜了一下,终于找到了答案,在Zend 论坛里一位Zend 员工明确地回复:"目前还没有针对 Thread-Safe 的PHP 5.3发布相应的Zend Debugger的计划",这个帖子?里,另一位Zend员工针对用户在Thread Safe 版PHP 5.3 安装 Zend Debugger失败的原因做了更详细的解释: ?Zend stopped supporting the thread safe architecture when Microsoft also decided to implement its PHP engine with the fast-cgi architecture which means non-thread-safe. 他建议用户用安装Zend Server(目前已经支持PHP 5.3)--? Zend Server包含的是Non Thread Safe 版的PHP.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
