Purpose
Use PHP to generate HTML documents, support label nesting and indentation, and support label custom attributes
Cause
This thing was indeed written on a whim. It was originally intended to output HTML fragments, but later it was simply written as a function that can output complete HTML;
I am very satisfied with the indentation mechanism inside. , if you find it useful, you can take a look at
p.s. Now the front-end and back-end are truly separated (vue, nodejs, webpack...), just use this thing if you like it, forget it if you don’t like it~
Supported tags
html, head, meta, title, body, input, select/option, form, table, div, comments, and custom tags (appearing in pairs tag), and a lot of attributes (introduced below)
Implementation
Overall
1. Each Tags correspond to a class, such as the tag , which corresponds to a class called html
2. I have put all the useful attributes in tags into a class, and provided methods to obtain them. Attributes assigned a value
Nested indent
I designed a class for each tag, such as the table tag, there is a class called table with it Corresponding to
, each class generally has the following three important members:
1. The indentation value of this tag
2. The method of outputting the final string of this tag , out()
3. To add a subtag to this tag, append()
where append() receives the object of the subtag, and finally calls $html-> ;When out(), the out() method in each sub-label object will be called in sequence, and the indent value will also be passed from the upper class to the lower class and accumulated;
In addition, each class Contains attribute classes (calss attribute). The indentation value of each class is inherited from the attribute class, so if the indentation in the attribute class is modified, the indentation of all classes will change accordingly
You can also add your own indentation value to the label class to override the unified indentation value
Attribute
My solution here is to define a Class (calss attribute), which contains
1. Attributes that tags may have
2. Corresponding setXxx method
3. Assemble non-empty attributes into a string Method
4. In order not to affect the next display, there will be a special clearing method to clear all the previously assigned attributes
In this case, when defining the label attribute, what is needed Assign a value. If you do not assign a value if it is not needed, it will not be displayed in the final HTML code.

PHP and Python: Different Paradigms ExplainedApr 18, 2025 am 12:26 AMPHP 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 and Python: A Deep Dive into Their HistoryApr 18, 2025 am 12:25 AMPHP 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.
Choosing Between PHP and Python: A GuideApr 18, 2025 am 12:24 AMPHP 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 and Frameworks: Modernizing the LanguageApr 18, 2025 am 12:14 AMPHP 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.

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AMPHP 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.
How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AMIn 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 vs. Python: Use Cases and ApplicationsApr 17, 2025 am 12:23 AMPHP 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.
