Get version from composer.json [Symfony]

Question

I wonder if there is a way to get the composer.json version from a controller with Symfony. My composer.json looks like:

{
    "name": "myProject",
    "version": "0.0.0",
    "description": "myProject description",
    "license": "AGPL-3.0",
    "type": "project",
    "require": {
        "php": "^7.1.3",
        ...
    }
}

I can't find any reference to this.

PS: I'm using Symfony 4.

You can do something like this:

$filename = $this->getParameter('%app.kernel_dir%') . '/../composer.json';
$composerData = json_decode(file_get_contents($filename), true);

$version = $composerData['version'];

The variable should then containv the value 0.0.0 from your example.

This assumes that your controller extends the base Controller to access the %app.kernel_dir% parameter. If not, you could just as well use the relative path from your controller or something else to determine the location of the composer.json
