PHP Read AND Write Binary Stream Package

二进制流读写工具，封装了一些常用的二进制读写方法

  • English Version

  • 使用说明

    • 读取二进制流的相关方法
      use BinaryStream\BinaryWriter;
$writer = new BinaryWriter();
$writer->writeUTFString( str_repeat("It`s long string,", 200) );
$writer->writeUTFString("");
$writer->writeInt32(-90);
$writer->writeDouble(800);
$writer->writeFloat(3.88511321334343434324443324321);
$writer->writeDouble(148.3243413243132134343213244313132);
$writer->writeChar("s");
$byteWriter = new ByteWriter();
$byteWriter->writeByte(120);
$byteWriter->writeInt16ToByte(65530);
$byteWriter->writeInt32ToByte(1526456146);
$writer->writeByteObject($byteWriter);

    • 注：

      1. 程序默认的字节序是大端字节序你可以使用 setBinaryModel() 方法修改字节序
       $write->setBinaryModel(BinaryCode::LITTLE_ENDIAN | BinaryCode::BIG_ENDIAN);
      1. 程序默认存储本地流文件的方式是 FILE_BINARY 你可以使用 store() 改变存储模式
         $writer->store(FILE_APPEND);
  //or 
  $writer->store(FILE_TEXT);
  //or
  $writer->store(FILE_APPEND | LOCK_EX);
    • 读取二进制流的方式
      注：读取顺序一定要匹配写入的顺序
      $reader = new BinaryReader($writer->getWriteStream());
$res[] = $reader->readUTFString();
$res[] = $reader->readUTFString();
$res[] = $reader->readInt32();
$res[] = $reader- >readDouble();
$res[] = $reader->readDouble();
$res[] = $reader->readFloat();
$res[] = $reader->readDouble();
$res[] =  $reader->readChar();
$byteReader = $reader->readByByteReader();
$res[] = $byteReader->readByte();
$res[] = $byteReader->readBytesToShort();
$res[] = $byteReader->readByteToInt32();

  • 如何使用

可以通过Composer命令

composer require eouna/pack-binary

安装此工具包
