进入解压目录执行: phpize
./configure
make
make install
# please add following line to your php.ini
extension=protobuf.so
重启PHP
phpinfo() 就可以看到 protobuff扩展
如何使用?
保存
首先建方proto文件 foo.proto文件
message PhoneNumber {
required string number = 1;
required int32 type = 2;
}
message Person {
required string name = 1;
required int32 id = 2;
optional string email = 3;
repeated PhoneNumber phone = 4;
}
message AddressBook {
repeated Person person = 1;
}
然后用命令生成
php protoc-php.php foo.proto
这时候会生成一个pb_proto_foo.php文件
下面具体就应用 。
假如与JAVA通信。protobuffer 保存php文件test.php如:
require_once 'pb_proto_test.php';
$packed = curlGet('http://10.0.247.113:8080/testweb/proto'); //此处是JAVA返回的buffer信息
$foo = new AddressBook();
try {
$foo->parseFromString($packed);
} catch (Exception $ex) {
die('Parse error: ' . $e->getMessage());
}
$pb = $foo->getPerson();
//print_r($pb);
//print_r($pb[0]);
echo $pb[0]->getName() .' _ '.$pb[0]->getId() .' _ ';
print_r($pb[0]->getPhone());
PHP调用修改buffer数据
----------------------------
require_once 'pb_proto_test.php';
$foo = new Person();
$foo->setName('xiaojh');
$foo->setId(200);
$foo->setEmail('[email protected]');
//$foo->appendPhone(2);
$packed = $foo->serializeToString();
$foo->clear();
try {
$xiao = $foo->parseFromString($packed);
//print_r($xiao);
} catch (Exception $ex) {
die('Upss.. there is a bug in this example');
}
echo $foo->getName();
echo $foo->getPhone()->number;
$foo->dump();
PHP内部调用
