PHP写的二元响应 [英] PHP write binary response

问题描述

在PHP是有写二进制数据响应流的方式，
结果
等的等效（C＃ASP）
结果

  System.IO.BinaryWriter二进制=新System.IO.BinaryWriter（Response.OutputStream）;
Binary.Write（（System.Int32 1））; // 01000000
Binary.Write（（System.Int32）1020）; // FC030000
Binary.Close（）;
 

结果
结果
那么我想能够读取C＃应用程序的响应，如

  System.Net.HttpWebRequest请求=（System.Net.HttpWebRequest）System.Net.WebRequest.Create（URI）;
System.IO.BinaryReader二进制=新System.IO.BinaryReader（Request.GetResponse（）GetResponseStream（））;
System.Int32 I = Binary.ReadInt32（）; // 1
I = Binary.ReadInt32（）; // 1020
Binary.Close（）;
 

解决方案

在PHP中，字符串和字节数组是同一个。使用包以创建一个字节数组（串），您可以再写入。一旦我意识到，生活变得更容易。

  $ my_byte_array =包（LL，为0x01000000，0xFC030000）;
$ FP =的fopen（somefile.txt，W）;
FWRITE（$ FP，$ my_byte_array）;//或者只是呼应到stdout
回声$ my_byte_array;
 

In php is there a way to write binary data to the response stream,
like the equivalent of (c# asp)

System.IO.BinaryWriter Binary = new System.IO.BinaryWriter(Response.OutputStream);
Binary.Write((System.Int32)1);//01000000
Binary.Write((System.Int32)1020);//FC030000
Binary.Close();

I would then like to be able read the response in a c# application, like

System.Net.HttpWebRequest Request = (System.Net.HttpWebRequest)System.Net.WebRequest.Create("URI");
System.IO.BinaryReader Binary = new System.IO.BinaryReader(Request.GetResponse().GetResponseStream());
System.Int32 i = Binary.ReadInt32();//1
i = Binary.ReadInt32();//1020
Binary.Close();

解决方案

In PHP, strings and byte arrays are one and the same. Use pack to create a byte array (string) that you can then write. Once I realized that, life got easier.

$my_byte_array = pack("LL", 0x01000000, 0xFC030000);
$fp = fopen("somefile.txt", "w");
fwrite($fp, $my_byte_array);

// or just echo to stdout
echo $my_byte_array;
