Smarty include怎么用?
{include}用于载入其他模板到当前模板中。 在包含模板中可用的变量,载入后在当前模板仍然可用。
{include}必须设置file 属性,设置载入的文件资源路径。
设置了可选的assign属性,将{include}模板的内容赋值到变量,而并非输出。 与{assign}操作相似。
包含模板时,可以像使用属性一样设置传递的变量。 这样传递的变量,作用范围仅限于包含的模板内。 属性传递的变量将覆盖原包含模板的同名变量。
你可以在当前模板内使用包含模板的全部变量。 但是如果包含模板内有修改或者新建变量,那么这些变量只有包含模板的作用范围,而不可以是当前{include}模板中使用。 这种默认的设置,可以通过在包含模板时设置{include}的作用范围属性,或者 在修改或新增变量时通过{assign}的作用范围属性来设定。 后者在需要包含模板返回值时比较有用。
当文件不在$template_dir目录中时, 使用资源的语法来{include}包含文件。
使用例子:
<html> <head> <title>{$title}</title> </head> <body> {include file='page_header.tpl'} {* body of template goes here, the $tpl_name variable is replaced with a value eg 'contact.tpl' *} {include file="$tpl_name.tpl"} {* using shortform file attribute *} {include 'page_footer.tpl'} </body> </html>
include使用:
在php文件中可以这么写:
$header=$path.'header.dwt'; $smarty->assign('header',$header);
在模板文件中则这样写:
{include file=$header}

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
