PHP Error: Call to a member function count() on array

[bshaffer]

What version of protobuf and what language are you using?

PHP - The latest (main)

What operating system (Linux, Windows, ...) and version?

MacOSX

What runtime / compiler are you using (e.g., python version or gcc version)

Both native and protobuf c-extension for PHP

What did you do?

Calling setX($val) on a deprecated repeated field or map when the php extension is enabled results in a PHP error:

PHP Error: Call to a member function count() on array

This is because the c-extension seems to have different behavior than the PHP native library - the return type of GPBUtil::checkRepeatedField is of type RepeatedField in the native library, but in the extension it is array.

1. Generate a deprecated repeated field or map field in PHP
2. Make sure the protobuf.so c-extension is installed for PHP
3. Call the setter of the deprecated field
4. You'll get a PHP fatal error

I have the same issue, as a work around I create the RepeatedField manually when needed

$result = new RepeatedField(GPBType::MESSAGE, Subscription::class);

foreach ($subscriptions as $subscription) {
    $result[] = $this->responseTransformer->transform($subscription);
}

return (new ListSubscriptionsResponse())->setSubscriptions($result);
