PHP 8.0
PHP 8.0 brings new features, syntax additions, and bugfixes. For details on what’s new in this version, see the release announcement. For details on migrating your code, refer to the Migrating from PHP 7.4.x to PHP 8.0.x guide.
Named Arguments
Named arguments allow passing arguments to a function based on the parameter name rather than position. This way, function calls become self-documenting and arguments order becomes arbitrary.
In a function call, you can use the provided quick-fix Alt+Enter to add parameter names either one by one or to all arguments at once. If there are arguments in the list whose passed value matches the default value, PhpStorm highlights them as unused and provides a quick-fix to delete them.
Attributes
With attributes, you can provide structured, syntactic metadata to declarations of classes, properties, functions, and so on. Unlike PHPDoc comments, attributes are supported and validated on the language level.
Several code inspections help to ensure that attributes are used correctly:
The Class cannot be used as attribute inspection verifies that a class is annotated with #[Attribute] in its arguments declaration.
The Non-applicable attribute target declaration inspection verifies that the attribute is annotated with #[Attribute::Target] in its arguments declaration, and is therefore applied to the correct target such as a class or a method,
The Non-repeatable attribute inspection highlights attributes that are repeated without the Attribute::IS_REPEATABLE flag set in its arguments declaration.
PhpStorm provides custom open-source PHP 8 attributes. To use them in your project, add a jetbrains/phpstorm-attributes Composer dependency as described in Install Composer dependencies.
Union types
A Union Type accepts values of multiple different types rather than a single one. Union types are specified as Type1|Type2|. and can be used in all places where regular types are accepted. All existing PhpStorm coding assistance features fully support union types.
If a union type is provided via PHPDoc, PhpStorm offers a quick-fix Alt+Enter for converting it to a native union type.
With natively declared union types, PhpStorm can analyze calls and detect problem areas. The checks work on all levels: properties, arguments, and return values.
Constructor property promotion
PhpStorm verifies that promoted properties are used in accordance with the PHP 8 constraints. For example, a promoted property cannot be declared outside a constructor or inside an abstract constructor, and variadic parameters cannot be promoted.
Match expression
A match expression is similar to switch but provides safer semantics and can return a value. PhpStorm detects switch statements that can be converted to match expressions and provides a dedicated quick-fix Alt+Enter to do this.
Several code inspections help to ensure that match expressions are used correctly:
The Unused ‘match’ condition inspection highlights the conditions that are never matched and suggests deleting them.
The Unused condition inspection detects duplicate conditions that will never run. You can navigate between them and remove either the entire arm or only the duplicate value from a list of values.
The Duplicate arm in ‘match’ expression inspection detects identical bodies in different arms, which can be merged into one to reduce the size of the block.
The ‘match’ expression can be replaced with ternary expression inspection will detect expressions with a single arm and a default arm and let you replace them with ternary expressions.
If a match expression only has a default arm, then it is probably redundant. The Redundant ‘match’ expression inspection will highlight such expressions and let you remove them.
Nullsafe operator
PhpStorm verifies that the nullsafe operator is not erroneously used in write context or as a reference.
Non-capturing catches
Starting with PHP 8, you can catch exceptions without capturing them to variables. The Unused local variable inspection detects the variables that are not used inside the catch statement and provides a quick-fix Alt+Enter to remove them:
Throw expression
Using ::class on objects
New functions for strings
Как я могу установить версию PHP в PHPStorm?
можно ли установить значение версии PHP, скажем 4.0+ и иметь функции выделения PHPStorm, которые не будут работать с самой старой версией? Например, для PHP4 это должно выделить static function etc. У меня есть установка PHP на моем ПК, но я не хочу устанавливать более старую версию PHP для каждого небольшого скрипта, который я должен создать.

Итак, вы хотите выделить все куски кода, которые не будут работать в версии, которую вы пишете, верно? Это можно сделать в:
или в более новых версиях PhpStorm:
затем выберите свою версию, например, 7.0
Это очень полезно, когда ваш местный находится в 7.0, например, но производство находится в 5.5. Таким образом, phpstorm предупредит вас, какие части не будут работать в производстве.
В случае, если ваше поле отключено.
вероятно, ваши настройки » синхронизировать настройки IDE с композитором.формат JSON» включена
вы можете изменить свою версию PHP в composer.json file
или отключить настройки в этом пути
откройте диалоговое окно настройки, выбрав File / Settings, нажмите кнопку PHP под Языки И Фреймворки. Откроется страница PHP.
теперь вы можете сделать 2 вещи:
можно использовать ответ Алехандро Морено, но иногда вы не сможете изменить уровень PHP из закрытого выпадающего списка.
вы можете отключить «синхронизировать настройки IDE с composer.флажок в JSON» с:
и после применения открытого
здесь вы можете изменить уровень PHP с открытого раскрывающийся.
на Mac он находится под PHPStorm, Preferences, Languages & Framework, PHP
вы можете установить это для каждого проекта, как это изложено @Alejandro Moreno.
существует также глобальная настройка, которая позволяет установить уровень языка PHP для всех новая проектов.
здесь вы можете установить желаемый уровень для всех будущих проектов 🙂

Php language level phpstorm
The page and all the pages under this node are available only when the PHP plugin is enabled. The PHP plugin is bundled with PhpStorm and activated by default. If the plugin is disabled, enable it on the Installed tab of the Settings/Preferences | Plugins page, as described in Managing plugins.
Use this page to configure PHP development and unit testing support in the project by choosing one of the available PHP interpreters, see Configure local PHP interpreters and Configure remote PHP interpreters.
No correlation between the PHP version used in the project and the language level is enforced. Although the language version of each interpreter is detected automatically, you can still tell PhpStorm to provide you with coding assistance that corresponds to a different language level. However, if you attempt to use a code construct that is not supported by the specified language level, PhpStorm suggests a Switch to PHP quick-fix.
When you open an existing project, PhpStorm analyzes it for the language features used and sets the appropriate language level automatically.
You can also set the PHP language level directly from the status bar.
In this list, choose the PHP interpreter to use in the current project by default. The list contains all the currently configured local and remote PHP interpreters. See Configure local PHP interpreters and Configure remote PHP interpreters for details.
Click this button next to the CLI Interpreter list to create a new PhpStorm-wide PHP installation configuration in the CLI Interpreters dialog that opens.
Include Path Tab
PHP Runtime Tab
The area lists the available PHP stubs, which are normal, syntactically correct PHP files containing annotated function, method, and class signatures, constant definitions, and so on. PHP stubs are added to PhpStorm’s internal knowledge to enhance coding assistance for all the Standard PHP Library components as well as for common extensions.
Use the checkboxes next to each item to enable/disable the corresponding stub.
To load the set of stubs that matches the set of loaded extensions for the currently configured CLI interpreter, click the Sync Extensions with Interpreter button. For details on configuring interpreters, see Configure local PHP interpreters and Configure remote PHP interpreters.
In the Project tool window, the currently loaded stubs are displayed under the External Libraries node.
PHP stubs are open-source, and you can contribute to their development. See the blog post for details.
Advanced Settings Area
PHP stubs are available as a Composer package, and can thus be declared and installed as a dependency for some third-party package. In this case, they are stored under the vendor/jetbrains/phpstorm-stubs folder inside your project.
To prevent conflicts between the Composer package stubs and PhpStorm bundled stubs, do one of the following:
To use the Composer package stubs in your project, explicitly provide the path to their location in the Default stubs path field.
To use the PhpStorm’s bundled PHP stubs, make sure that the Default stubs path field is cleared and the vendor/jetbrains/phpstorm-stubs folder is excluded from the project.
If the Add packages as libraries is disabled, you can exclude the stubs package folder manually. To do this, in the Project view, right-click the vendor/jetbrains/phpstorm-stubs folder and select Mark Directory as | Excluded from the context menu.
For details in working with Composer in PhpStorm, refer to Composer dependency manager.
Analysis Tab
Use this tab to configure the behavior of certain PhpStorm inspections.
Exception Analysis
Use this list to set the desired exception analysis depth level. By default, 1 is selected, in which case PhpStorm reports the unhandled exceptions for the parent method throwing an exception, as well as the methods directly calling it. Selecting larger values allows you to drill down deeper into the calls hierarchy.
If 0 is selected, the exception analysis is limited to the parent method.
Values greater than 1 might negatively affect the IDE’s performance.
Select this checkbox to have PhpStorm skip certain method calls in the instance creation expressions during exception analysis:
Method calls only having strings or constants as parameters are skipped:
Method calls having variables, integers, arrays, and so on as parameters are not skipped:
Custom Format Functions
Use this section to include your custom string formatting functions into the Format function parameters mismatch inspection analysis scope. This inspection reports the mismatches between format function parameters and specification conversion entries and by default analyzes the usages of the standard PHP printf and sprintf functions.
Click this button to add a new function record to the custom format functions list. In the Add Custom Format Function dialog that opens, provide the name of a class method or function and specify the index of the argument where your formatting template resides.
Click this button to remove a function record from the custom format functions list.
Click this button to edit the selected function record.
Include Analysis
The specified path will be used in code completion for the functions/methods that use file paths as arguments (for example, require() or include() ). If the path is left blank, code completion will suggest the paths relative to the project root.
Commonly, this setting should be modified in case the document root folder defined by your web server configuration is different from the PhpStorm project root folder.
