Access PHP function documentation through the code editor

The code editor can easily view PHP function documents and improve development efficiency. After installing and enabling the PHP IntelliSense extension in VSCode, hover the cursor over the function name to view the documentation. After installing the DocBlockr plug-in in Sublime Text and configuring shortcut keys, hover over the function name and press the shortcut key (such as Ctrl Shift D) to view the document. An example is to obtain the string length through the strlen() function, and hover over the function name to view the documentation.

Access PHP function documentation through the code editor

Introduction

Working with code When writing PHP code with an editor, it is crucial to obtain function documentation in a timely manner. This tutorial will teach you how to use a code editor to access PHP function documentation, improving your development efficiency.

Access to PHP function documentation in VSCode

1. Install the PHP IntelliSense extension

• Open Visual Studio Code (VSCode).
• Search for "PHP IntelliSense" in the extension panel.
• Click the "Install" button to install the extension.

2. Enable extension

• Reload VSCode.
• Navigate to File > Preferences > Settings (on Mac) or File > Settings (on Windows).
• Search for "PHP" in the search bar.
• Find the "PHP IntelliSense" setting and enable it.

3. Use the code editor to access documentation

• In PHP code, hover the cursor over the name of the function whose documentation you want to view .
• VSCode will display function documentation, including type annotations, descriptions, and parameters.

Access to PHP function documentation in Sublime Text

1. Install the DocBlockr plug-in

• Open Sublime Text.
• Navigate to "Package Control" > "Install Package" in the menu bar.
• Search for "DocBlockr" and install the plugin.

• Go to "Preferences" > "Key Bindings" > "User".
• Add the following lines:

{ "keys": ["ctrl+shift+d"], "command": "docblockr_function_hover" }

3. Use the code editor to access the document

• In the PHP code, move the cursor Hover over the name of the function whose documentation you want to see.
• Press your configured shortcut key (in this case Ctrl Shift D).
• Sublime Text will display function documentation, including type annotations, descriptions, and parameters.

Practical case

Get the string length

// 悬停在 strlen() 函数名称上查看文档
$strlen = strlen($string);

Conclusion

By using the code editor to access PHP function documentation, you can quickly and easily gain insights into a function's behavior. This will significantly improve your development experience, allowing you to write more efficient and error-free code.
