以下是一个纯 PHP 编写的通用 Protobuf 二进制生成器，支持：

varint
fixed32
fixed64
length-delimited（如字符串、嵌套 message）
嵌套结构 (nested)
多字段 repeated

✅ 封装器代码（可直接用）

<?phpfunction writeVarint($value) {$result = '';while (true) {if (($value & ~0x7F) === 0) {$result .= chr($value);break;} else {$result .= chr(($value & 0x7F) | 0x80);$value >>= 7;}}return $result;
}function writeFieldHeader($fieldNum, $wireType) {return writeVarint(($fieldNum << 3) | $wireType);
}function writeVarintField($fieldNum, $value) {return writeFieldHeader($fieldNum, 0) . writeVarint($value);
}function writeFixed32Field($fieldNum, $hex) {if (strlen($hex) !== 8) throw new Exception("fixed32 hex 必须为 8 位");return writeFieldHeader($fieldNum, 5) . hex2bin($hex);
}function writeFixed64Field($fieldNum, $hex) {if (strlen($hex) !== 16) throw new Exception("fixed64 hex 必须为 16 位");return writeFieldHeader($fieldNum, 1) . hex2bin($hex);
}function writeLengthDelimitedField($fieldNum, $value) {return writeFieldHeader($fieldNum, 2) . writeVarint(strlen($value)) . $value;
}function buildMessage($fields) {$message = '';foreach ($fields as $field) {$fieldNum = $field['field'];$type = $field['type'];$value = $field['value'];switch ($type) {case 'varint':$message .= writeVarintField($fieldNum, $value);break;case 'fixed32':$message .= writeFixed32Field($fieldNum, $value);break;case 'fixed64':$message .= writeFixed64Field($fieldNum, $value);break;case 'string':$message .= writeLengthDelimitedField($fieldNum, $value);break;case 'bytes':$message .= writeLengthDelimitedField($fieldNum, hex2bin($value));break;case 'nested':$nested = buildMessage($value);  // 递归生成嵌套$message .= writeLengthDelimitedField($fieldNum, $nested);break;default:throw new Exception("不支持的字段类型: $type");}}return $message;
}

示例调用方式

$protobuf = buildMessage([['field' => 1, 'type' => 'varint', 'value' => 123],['field' => 2, 'type' => 'fixed64', 'value' => '0011223344556677'],['field' => 3, 'type' => 'string', 'value' => 'hello'],['field' => 4, 'type' => 'bytes', 'value' => 'deadbeef'],['field' => 5, 'type' => 'nested', 'value' => [['field' => 1, 'type' => 'string', 'value' => 'inner']]]
]);echo base64_encode($protobuf);

以下是一个 JSON 转 Protobuf 结构数组 的示例转换器，用于搭配你已有的 buildMessage() 使用：

✅ 1. JSON → PHP 数组结构转换器

🔧 示例 JSON 格式

[{ "field": 1, "type": "varint", "value": 123 },{ "field": 2, "type": "fixed64", "value": "0011223344556677" },{ "field": 3, "type": "string", "value": "hello" },{"field": 4,"type": "nested","value": [{ "field": 1, "type": "string", "value": "inner" }]}
]

✅ 加载并构造的 PHP 代码

function buildFromJson($jsonStr) {$decoded = json_decode($jsonStr, true);if (!is_array($decoded)) {throw new Exception("无效 JSON 格式");}return buildMessage($decoded);
}

✅ 完整示例组合用法：

include 'protobuf_builder.php'; // 假设你把封装器写到这个文件里$json = '[{ "field": 1, "type": "varint", "value": 123 },{ "field": 2, "type": "fixed64", "value": "0011223344556677" },{ "field": 3, "type": "string", "value": "hello" },{"field": 4,"type": "nested","value": [{ "field": 1, "type": "string", "value": "inner" }]}
]';$protobuf = buildFromJson($json);
echo base64_encode($protobuf);

✅ 输出说明

这段代码会输出一段 符合 JSON 结构的 Protobuf 二进制串，你可用于发送、调试、对比：
