Smarty reserved variable usage analysis, smarty variable usage
The examples in this article describe the usage of Smarty reserved variables. Share it with everyone for your reference, the details are as follows:
The {$smarty} variable does not need to be allocated. It can be used directly in the template to access some special template variables. There are many variables, such as: page request variables $_GET, $_POST, $_REQUEST, $_SESSION, $ _COOKIE, and some environment variables such as $_ENV and $_SERVER, which can be obtained directly through the following methods:
{$smarty.get}
Same as $_GET to get url parameters
For example: $_GET['page'] Get
through {$smarty.get.page}{$smarty.post}
Same as $_POST to get parameters
{$smarty.request}
Same as $_REQUEST to get request parameters
{$smarty.cookie}
Same as $_COOKIE to get cookies
{$smarty.session}
Same as $_SESSION to get session
{$smarty.server}
Same as $_SERVER to get server variables
{$smarty.env}
Same as $_ENV to get environment variables
{$smarty.now}
Same as time(), get timestamp
{$smarty.const}
Directly access PHP constants, such as {$smarty.const.__FILE__}
{$smarty.capture}
Template output captured via the built-in {capture}...{/capture} function can be accessed by {$smarty.capture.name}
{$smarty.section} {$smarty.foreach}
Used to access the loop attributes of {section} and {foreach} respectively. There are some first, last, index and other attribute values available
{$smarty.template}
Return the current template name
{$smarty.version}
smarty version
{$smarty.ldelim} {$smarty.rdelim}
is used to print the left delimiter and right delimiter, class {ldelim}{rdelim}

I hope this article will be helpful to everyone’s PHP program design based on smarty templates.

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.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
