Paypal X Adaptive Pay FundingConstraint for PHP

The following code is an example of adding the FundingConstraint objects for a payRequest with Paypals new Adaptive Payments. I hope this helps.

$payRequest->fundingConstraint = new FundingConstraint();

//$payRequest
//    ->fundingConstraint
//    ->allowedFundingType
//    ->fundingTypeInfo
//    ->fundingType = "BALANCE";

$payRequest
    ->fundingConstraint
    ->allowedFundingType
    ->fundingTypeInfo
    ->fundingType = "ECHECK";
