Notepad++ auto-completion for WordPress, it contains about 900 global functions with the definitions of functions, return types, brief descriptions, and parameters. The data is taken from the comments in the source code and from the official online documentation. Deprecated functions and parameters are not added.

Wordpress keywords for autocomplete are merged with the default php keywords stored in php.xml. There are two XML files here, one with descriptions of functions, and the other without them. Rename the file that you want to php.xml and replace the /plugins/APIs/php.xml file ( create a backup of the original file in case you change your mind ).
