php - 将二进制字节转换为字符串

Question

我想要做什么： 1. 解压缩压缩文件。
2.将未压缩的文件字节插入数组。
3.将每个字节转换为字符。

编码：

<?php
$list = file_get_contents('http://www.getlist.xp3.biz/list3'); //get the contents of the compressed file
$list = gzuncompress($list); //Uncompress the file
$bytes = unpack('c*', $list); //unpack the bytes of list into array
$string = implode('', array_map('chr', $bytes)); //convert each byte to chr by implode and array_map functions
echo $string; //print results
?>

这段代码几乎可以工作。
结果： http://getlist.xp3.biz/getlist.php
让我们以这一行为例：

B~12ee397313ba2dd4f27fc1430744e615e4f83a44f9b206fb78fdf9b45dd9dc74fel profanador88's Room ar�7t��Bk

在行尾有一些有线字符：ar�7t��Bk

这个字符不是文本字节，某人（其他开发人员）转换了字节，他的 php文件返回包含更多信息的行：

{"ver":"26","id":"12ee397313ba2dd4f27fc1430744e615e4f83a44f9b206fb78fdf9b45dd9dc74f","name":"profanador88's Room","players":"1","max_players":"10","password":false,"country":"ar","latitude":"41.0186004639","longitude":"28.9647006989","distance":1168.7633}

我有id、roomname和国家代码（以及 werid 字符（=其他信息））。

在他的行中：版本、ID、名称、玩家编号、最大玩家编号、如果设置密码（布尔值）、国家代码、纬度、经度和距离。

正好还有7个。

也许ar�7t��Bk包含其他信息？
我认为其他信息在那里（100％），我只是不知道如何转换字节（奇怪的字符）。
我试图向其他开发人员询问这个奇怪的字符，但没有答案。
也许有人知道如何将此二进制文件转换为普通字符串，
也许这些信息可以提供帮助（其他开发人员的注释）：

the list is a compressed binary file
which you can obtain @ /list3
it is compressed with zlib deflate
after decompression the format is as follows: (wait a bit must open the source file)
1 byte ; list format version ( currently = 1 )
4 bytes ; skip this, you don't care about them
then follows a list of RoomInfo structures until the end of the file
this is the Roominfo structure:
data.writeShort(ver); //Vrsion Short
data.writeUTF(netID); //ID String
data.writeUTF(name); //ROOMNAME string
data.writeByte(players); //PLAYERS
data.writeByte(maxPlayers); //MaxPlayers
data.writeBoolean(password); //If isset password boolean
data.writeUTF(countryCode); //country code
data.writeFloat(latitude); //Float latitude
data.writeFloat(longitude); //Float longitude
that's all

我使用chr函数将字节转换为大字符串，嗨说字节不仅是字符串，
还有代表：Float，Boolean，Integer，Short的字节。
chr 是仅代表字符串的字节（我使用了它: $string = implode('', array_map('chr', $bytes));)，我可能需要在不使用此快捷方式的情况下通过 foreach 读取每个字节。
我的问题是：
是否有人知道如何修复代码并使其工作（使 php 打印丢失的其他信息（信息存在，但以字节为单位（不是字符串）））？
更新：
我认为我找到了将字节转换为短/布尔/浮点/整数的类，
现在我需要有人向我解释如何使用这个类（require('class.php')...code here），或者有人会尝试用这个类修复我的代码（我试图单独修复它，但我仍然不知道如何使用这个库或何时需要使用该库）。
