How can I set the PHP version in PHPStorm?

Question

Is it possible to set the PHP version value, say 4.0+ and have PHPStorm highlight functions that wouldn't work with the oldest version? For example, for PHP4 this should highlight static function etc. I have a PHP installation on my PC but I don't want to install an older PHP version for every small script I have to produce.

Thanks

Answer 1

so, you mean to highlight all pieces of code that will not work in the version you are writing it, right? That can be done in:

Preferences -> Languages & Frameworks > PHP

Or in newer versions of PhpStorm:

File -> Settings -> Languages & Frameworks > PHP

then select your version, for example, 7.0

This is very useful when your local is in 7.0, for example, but production is in 5.5. That way phpstorm will warning you which parts will not work in production.

Answer 2

In case your field is disabled.

Probably your settings "Synchronize IDE settings with composer.json" is enabled

You may change your PHP version in composer.json file

"require": {
    "php": ">=7.1.0",
}

OR disable your settings in this path

File -> Settings -> Languages & Frameworks > PHP > Composer

*If you change your composer.json file - As Félix Gagnon-Grenier commented, Keep in mind it has effects on the way packages will be required later

Answer 3

Open the Settings dialog box by choosing File | Settings, then click PHP under Languages & Frameworks. The PHP page opens.

Now you can do 2 things:

1. On the PHP page that opens you can set the "PHP Language Level".
2. You can install the PHP version that you wish locally by, for example, installing packages like wamp or xamp and then set the interpreter of your PHP on the PHP page that you opened. More info here

Answer 4

You can use Alejandro Moreno's answer, but sometimes you might not be able to change PHP level from closed dropdown.

You can disable "Synchronize IDE settings with composer.json" checkbox from:

File -> Settings -> Languages & Frameworks -> PHP -> Composer

And after applying again open

File -> Settings -> Languages & Frameworks -> PHP

Here You can change PHP level from opened dropdown.

Answer 5

On Mac, it is under PHPStorm, Preferences, Languages & Frameworks, PHP

Answer 6

You can set this per project, as outlined by @Alejandro Moreno.

There is also a global setting, that allows you to set the PHP Language Level for all NEW projects.

File --> Preferences for New Projects --> Languages & Frameworks --> PHP

Here you can set the desired level for all future projects :-)
