Here's my .proto file:
message HelloReply {
string message = 1;
}
Here's the output php from the protoc run with grpc_php_plugin:
<?php
# Generated by the protocol buffer compiler. DO NOT EDIT!
# source: helloworld.proto
namespace Helloworld;
use Google\Protobuf\Internal\GPBType;
use Google\Protobuf\Internal\RepeatedField;
use Google\Protobuf\Internal\GPBUtil;
/**

*/
class HelloRequest extends \Google\Protobuf\Internal\Message
{
/**

*/
private $name = '';
/**

*
* @param array $data {
* Optional. Data for populating the Message object.
*

*/
public function __construct($data = NULL) {
\GPBMetadata\Helloworld::initOnce();
parent::__construct($data);
}
/**

* @return string

public function getName()
{
return $this->name;
}
/**

* @return $this
*/
public function setName($var)
{
GPBUtil::checkString($var, True);
$this->name = $var;
return $this;
}
}
Here's a snipit from my code:
$name="test_name";
$request = new Helloworld\HelloRequest(array("name"=>$name));
echo "Name is " . $request->getName() . "\n";
var_dump($request);
Here's the output:
Name is test_name
object(Helloworld\HelloRequest)#3 (0) {
}
Why does var_dump not give me the value of "name" that is stored in the 'HelloRequest' object? How can I output all the properties and their values of an instance of a gRPC generated class? What is causing the properties of instances of classes that extend the gRPC 'Message' to be hidden?
I have tried type casting:
$strvar = (string) $request;
causes the following error:
PHP Recoverable fatal error: Object of class Helloworld\HelloRequest could not be converted to string in /home/........./php/greeter_client.php on line 42
A workaround may be
var_dump($request->serializeToJsonString())
