PhpStorm software configures the PHP language version

The following columnphpstorm tutorialwill introduce to you how to configure the PHP language version of PhpStorm. I hope it will be helpful to friends in need!

Problem Description

Generally speaking, the default PHP language version in PhpStorm is PHP 5.4, and PhpStorm will Files in the editor are automatically verified with this PHP version.

If we use the new features of PHP 7.0 (such as the null coalescing operator??) in the PHP file, then because PhpStorm cannot recognize the new feature when verifying the file, it will be in the corresponding location A warning sign (red wavy line) is displayed.

Although this will not have a big impact on our use of PhpStorm, this red warning looks unpleasant.

Solution

Modify the configuration of PhpStorm and adjust the PHP language version to PHP 7.0.

Click on the menu barFile → Settings → Languages & Frameworks → PHP, change the value of the PHP language level drop-down list to 7, and click OK to save.
