PHPDoc comments
For documentation comments, IntelliJ IDEA provides completion that is enabled by default. IntelliJ IDEA creates stubs of PHPDoc blocks when you type the /** opening tag and press Enter, or press Alt+Insert and appoint the code construct (a class, a method, a function, and so on) to document. Depending on your choice, IntelliJ IDEA will create the required tags or add an empty documentation stub.
If you need additional PHP-specific tags, IntelliJ IDEA provides code completion that suggests the tag names that are relevant in the current context. If a certain tag has multiple values, code completion provides a list of available values.
In PHPDoc comments, IntelliJ IDEA supports formatting options in compliance with the ZEND, PEAR, and other coding standards.
PHPDoc comments in your source code are available for Quick Documentation Lookup, which helps you get quick information for any documented symbol. You can open them for review in the Documentation tool window by pressing Ctrl+Q.
Enable documentation comments
Press Ctrl+Alt+S to open IDE settings and select Editor | General | Smart Keys.
In the Enter section, select or clear Insert documentation comment stub checkbox.
For Python, expand the Smart Keys node and select Python. Use the Insert type placeholders in the documentation comment stub option as required. Refer to the option description for details.
Generate a PHPDoc block for a code construct
To invoke generation of a PHPDoc block, do one of the following:
Place the caret before the required code construct (class, method, function, and so on), type the opening block comment
/**, and press Enter.In the editor context menu, select and choose the code construct to generate PHPDoc comments for.
Press Alt+Insert, then select Generate PHPDoc blocks, and choose the code construct to generate PHPDoc comments for.
IntelliJ IDEA analyzes the appointed code construct, extracts the data for parameters, return values, variables, or fields where possible, and on this basis generates a stub of a documentation block.
Describe the listed parameters and return values where necessary. IntelliJ IDEA checks and treats syntax in comments according to the code inspection settings.
Create tags in a PHPDoc comment block
IntelliJ IDEA analyzes the appointed code construct, extracts the data for parameters, return values, variables, or fields where possible, and on this basis generates a stub of a documentation block. If necessary, you can fill in the missing information.
In a PHPDoc block, select the desired empty line and press Ctrl+Space.
Select the relevant tag from the suggestion list.
If the entered tag has several values, press Ctrl+Space and select the desired value from the suggestion list.
Configure formatting inside PHPDoc comments
You can configure the appearance of PHPDoc comments, the presentation of class names, and the default tags sorting order. Note that the tag for properties is no longer configurable, the default @var tag is inserted automatically. See https://github.com/phpDocumentor/fig-standards/pull/55 for details.
In the Settings/Preferences dialog Ctrl+Alt+S, go to .
Switch to the PHPDoc tab an configure the desired appearance options by selecting or clearing the checkboxes.
Specify how you want IntelliJ IDEA to present class names for properties, function parameters, return and throws values, and so on, by selecting or clearing the Use fully-qualified class names checkbox.
If necessary, define how the generated PHPDoc tags should be sorted by selecting the Sort PHPDoc tags checkbox.

Using PHPDoc code inspections
IntelliJ IDEA provides a set of predefined code inspections targeted at PHPDoc blocks. These inspections check whether classes, methods, functions, variables, and constants are supplied with a PHPDoc comment and whether the tags in the comment match the documented item.
Enable or disable a PHPDoc inspection
In the Settings/Preferences dialog Ctrl+Alt+S, select .
On the Inspections page that opens, expand the PHPDoc node under PHP.
In the list of predefined inspections that opens, enable or disable an inspection by selecting or clearing the checkbox next to it.
Check that PHPDoc comments are provided for code constructs of a certain type
Enable the Missing PHPDoc Comment inspection.
In the Options area, select the checkboxes next to the required element type: class, method, function, variable, or constant.
To suppress reporting a Missing PHPDoc Comment error if a method or function does not contain any parameters or return values, select the Ignore PHPDoc without @param/@return checkbox.
