PHP SDK Fatal Error void must be compatible with

osa — Sat, 05 Jan 2019 02:20:26 GMT

Hi,

I've just cloned the php sdk from git and run 'composer update', but when I try the following command:

php PaymentTransactions/charge-credit-card.php

I get the folling error message:

PHP Fatal error:  Declaration of JMS\Serializer\JsonDeserializationVisitor::startVisitingObject(JMS\Serializer\Metadata\ClassMetadata $metadata, JMS\Serializer\object $object, array $type): void must be compatible with JMS\Serializer\Visitor\DeserializationVisitorInterface::startVisitingObject(JMS\Serializer\Metadata\ClassMetadata $metadata, JMS\Serializer\Visitor\object $data, array $type): void in authorize/vendor/jms/serializer/src/JsonDeserializationVisitor.php on line 14

php version is: 7.1.23

Any ideas ?

Thanks,

John

Hi,

Quick update, I've updated my version of PHP to 7.2 and it seems to have resolved the issue.

Regards,

John

@gulfamali

Has your sdk ever worked? Or is this your first time installing it? I don’t think PHP 7 is required for 1.9.6. Id have to look it up but I don’t think that’s your problem.
