我是一名网站美工,以前在学校是学过一些asp.net。现在公司的网站是php的,现在我想修改网站的一些功能,但是html中的代码实在让我疑惑,以前从没接触过这种类型。代码如下:
{{include file="header.html"}}
{{if $cat.parentid>0}}
{{ffcategory catid=$cat.parentid to=cate}}
{{else}}
{{ffcategory catid=$cat.catid to=cate}}
{{/if}}
{{ffpagelist field="jiaoling,address,price1,price2" to="datalist" order="`sort` asc,`create_time` desc"}}
- 当前条件下有{{$datalist.count}}所驾校 地图找附近驾校>
-
支持分校
{{$b.zhichi}}家
教练人数
{{$b.renshu}}名
通过率
{{$b.tgl}}%
{{ffpagelist pagesize=9 to="newsdata" field="zhichi,renshu,tgl" order="`sort` asc,`create_time` desc"}}
{{foreach from=$newsdata.info item=b key=k}}
{{/foreach}}
{{include file="footer.html"}}
我想知道{{}}中$b在哪定义的?方法与是从哪来的,整个代码都没交代吧
回复讨论(解决方案)
这是个模板文件,用户访问时会由与其对应的php文件读取这个模板文件,将其中的{{...}}替换成对应的php语句
{{...}}中的对象和变量也就替换成php中定义的对象和变量了

能够从这里看出对应的php文件在哪吗?

从模板文件中是看不出对应的php文件在哪的。
一般来说是在另外的目录中与模板文件同名或文件名类似的php文件。
你在该模板文件中加入
<script>document.write(location.href)</script>
就可知道该模板被谁使用了
这是php中的代码,我给你移动的php专区
用软件搜索整个项目关键字,谢谢大家

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.
