Detailed explanation of how to use ThinkPHP template engine
thinkphp system supports native PHP templates, and it has a built-in efficient compiled template engine based on XML. The template engine used by the system by default is the built-in template engine. For detailed usage of tags of this template engine, please refer to the template engine section. .
ThinkPHP has a built-in template engine to define template files and use advanced features such as loading files, template layout, and template inheritance.
Each template file will generate a compiled cache file during execution, which is actually a PHP file that can be run.

This way ThinkPHP completes the parsing of the page, which involves template instantiation, positioning, assignment, rendering and the use of tags.
View instantiation
None at the moment
Template assignment
Obviously, $name cannot be found when using it directly in the template of this variable. Templates must be assigned values using the assign method. Before executing the rendering output function, the assign method establishes a mapping relationship between the internal variables of the function and the template variables.

After assignment, you can use {$nameA} in the template file to output the variable.
Template rendering
When the data is ready to be rendered on the page, you also need to specify the html file as the rendering template and pass in the example parameter when executing the fetch method for the current function. .

Template tag
Using built-in tags in template files can help us loop and determine variables in the template . It uses a pair of curly braces {tag} {/tag} as the opening and closing tags. The tag attribute or value must be immediately followed between { and }, and the presence of spaces and newlines cannot be parsed during rendering.
The volist label is one of the built-in labels, usually used to loop through an array variable.

allName is a variable assigned through the template. It can now be used directly on the template. Obviously it is an array, and the volist tag performs a loop operation on it. .
Some commonly used attributes of volist tags:
array name | current element | |
allName | vo |
There are many built-in tags that are as useful as volist:

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
