"true" or "false" values not converted properly to boolean

[php-wizard]

Hello,
i am using codemix\yii2confload\Config class,
and i have this variable in my .env file:

PAYPAL_API_LIVE=false

at some point i read that variable
$live = Config::env("PAYPAL_API_LIVE");

Then i use it like this:

    curl_setopt($ch, CURLOPT_URL, "https://svcs" . ($live ? "" : ".sandbox") . ".paypal.com/AdaptivePayments/$method");

and the resulting CURLOPT_URL is going to be https://svcs.paypal.com/AdaptivePayments/ConvertCurrency
as the $live variable is the string "false" , which is true when evaluated as boolean.

How can i tell codemix\yii2confload\Config to parse "true" and "false" as Boolean ?

Use 0 and 1 instead and to be perfectly safe: $live = (bool) Config::env('PAYPAL_API_LIVE').
