| PHP language level |
In this drop-down list, specify the PHP functionality scope you are going to use. Each functionality scope is associated with PHP version that supports this functionality.
Depending on this choice, IntelliJ IDEA will provide your with the relevant coding assistance.
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 another 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. | |
