Setting up a WordPress project
The WordPress plugin is built-in and bundled with PhpStorm, but needs to be enabled on a per-project basis. When you open a WordPress project in PhpStorm for the first time, the IDE detects relevance of the WordPress plugin and prompts you to enable it.
Additionally, PhpStorm prompts you to configure the WordPress core installation you are working with as an Include Path to involve WordPress core files in indexing.
Download and install WordPress
Download the WordPress.zip archive at https://wordpress.org/download/.
Extract the archive:
If you are not going to run your WordPress application but just need to get coding assistance from PhpStorm, store the extracted files anywhere on your computer. In this case, you will have to configure the installation as an include path, refer to Configure include paths.
To have the possibility to run your WordPress application on a local Web server, store the extracted file to the document root of the server where the PHP interpreter is configured. For local development environment with the Apache HTTPD Web server, extract WordPress.zip to the htdocs folder.
To run your WordPress application on an in-place server, store the extracted file under the project root.
To run your WordPress application on a remote server, store the extracted files in your project and then configure automatic upload of them to the document root of the remote server.
Learn more about server access configurations, refer to Configure synchronization with a server. For more information about configuring upload to the server, refer to Upload and download files.
