File | Settings | PHP
Use this dialog box to configure PHP development and unit testing support in the project level by choosing one of the PHP installations configured at the IntelliJ IDEA level.
|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.

|Show phpinfo||Click this button to examine the installation details and view the full list of installation settings in a separate window. Actually, IntelliJ IDEA checks the installation and displays the result of executing the phpinfo command.|
