public static function Composer::getInstalledJson in Markdown 8.2

Retrieves the installed Composer JSON for a specific package.

@internal

Parameters

string $name: The package name for which version to check is installed.

array $comparisonJson: Optional. The JSON array to look for if the specified name doesn't exist. This can happen if installing an older package version where it uses an older package name. Unless the user explicitly installed that older package name, Composer will default to the newer/current package name in its installed.json file.

Return value

string|void The installed version or NULL if not installed.
