Is there a sniff to disallow "variable variable"?

Looking to disallow things like:

$$variable

With two dollar signs.

Thank you!

This should be super simple with custom phpstan rule:


use PhpParser\Node\Expr\Variable;
use PhpParser\Node;
use PHPStan\Analyser\Scope;
use PHPStan\Rules\Rule;

/**
 * @implements Rule<Variable>
 */
class CamelCaseFieldNamingRule implements Rule
{

    public function getNodeType(): string
    {
        return Variable::class;
    }

    /**
     * @param Variable $node
     * @return string[]
     */
    public function processNode(Node $node, Scope $scope): array
    {
        if (!is_string($node->name)) {
            return ['Expression for variable name is not allowed!'];
        }

        return [];
    }

}
