New Project: PHP Empty Project
The right-hand pane of the Project Category and Options dialog looks as follows when you choose PHP in the left-hand pane and then choose PHP Empty Project from the list in the right-hand pane.
The feature is supported only in the Ultimate edition when the PHP plugin is installed and enabled. The plugin is not bundled with IntelliJ IDEA, but it can be installed from the JetBrains plugin repository as described in Managing plugins.
PHP Language Level
| In this drop-down list, specify the PHP functionality scope to get coding assistance for. Each functionality scope is associated with the PHP version that supports this functionality. Currently PHP 5.3, PHP 5.4, PHP 5.5, PHP 5.6, PHP 7, PHP 7.1, PHP 7.2, PHP 7.3 and PHP 7.4 levels are supported. |
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 IntelliJ IDEA 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, IntelliJ IDEA suggests a Switch to PHP <version> quick-fix.
From this drop-down 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 Configuring Local PHP Interpreters and Configuring Remote PHP Interpreters for details.
