Creating PHP classes

In the Project tool window Alt01, select the directory in which you want to create a new PHP class and press AltInsert.

Alternatively, right-click the corresponding directory and select New from the context menu, or select File | New from the main menu.

In the New window that opens, select PHP Class to open the Create New PHP Class dialog.

In the Create New PHP Class dialog, fill out the fields as follows:

• Name: type the name of the class to be created.

  PhpStorm automatically fills in the specified name in the File name field. Additionally, PhpStorm sets the Template value automatically in case the provided class name follows the standard convention (that is, NameClass for classes, NameInterface for interfaces, and NameTrait for traits).

• Namespace: specify the namespace to create the class in, By default, the field shows the namespace that corresponds to the folder from which the class creation was invoked.

  You can choose <global namespace> from the list or change the namespace manually. Keep in mind that this may cause loading problems, since such namespace hierarchy will not meet the PSR-4 standards.

  You can also change the folder to store the file that will implement the new class, the change will also be reflected in the Namespace field.

• Template: select the template for the created file. The available options are:

  • Class

  • Interface

  • Trait

  • Enum (available only with PHP 8.1 or later)

  • Your custom manually created file templates with the PHP file extension, if any.

    To set such a template as a default, select the Use as a default template checkbox. The default template will be selected automatically the next time you invoke the creation of a new class.

• File extension: select the file extension from the list

If you are creating a class or an interface, optionally choose the parent classes for it in the Parent classes area.

• In the Extends field, type the name of the parent class that the current class extends. To use code completion, press CtrlSpace.

• In the Implements area, choose the interfaces that the created class implements (or the created interface extends):

  • To add an interface, click or press AltInsert. In the Choose Class dialog that opens, search for the desired interface either by name or by using the project tree view.

  • To remove an interface, click or press Delete.

Click OK to save the changes. A new class is created according to the selected template, with the specified namespace declaration added automatically.
