使用YAK Pro混淆PHP代码

YAK Pro可以用来混淆PHP源代码，混淆之后增加破解难度。

项目地址：https://github.com/pk-fr/yakpro-po

YAK Pro需要运行在php >= 7.0环境下，但混淆过后的代码可以运行在php 5.2 到 php 7.3，实际上PHP8也是可以运行的。

安装教程

需要先安装Git软件。不安装Git软件，就需要从Github上下载代码压缩包，解压后使用也是可以的。

下载源代码：

git clone https://github.com/pk-fr/yakpro-po.git

进入到项目文件夹下：

cd yakpro-po

下载PHP-Parser：

git clone https://github.com/nikic/PHP-Parser.git --branch 4.x

查看是否安装成功：

php yakpro-po.php

Info:   Using [C:\dev\nginx\html\test\yakpro-po\yakpro-po.cnf] Config File...
Info:   yakpro-po version = 2.0.14
Error:  source_directory and target_directory not specified!
        neither within command line parameter,
        nor in config file!

现在就可以混淆代码了

假设test.php的源代码如下：

<?php
/*--------------------------
    simple test program !
---------------------------*/
$hello      = "hello ";
$world      = "world ";
$what       = "what ";
$a          = "a ";
$beautiful  = "beautiful ";
$day        = "day ";

for($i=0;$i<=7;++$i)        // small loop!
{
    echo $hello;    echo $world;                                echo PHP_EOL;
    echo $what;     echo $a;    echo $beautiful;    echo $day;  echo PHP_EOL;
}
echo "that's it!".PHP_EOL;

执行混淆命令，将混淆后的文件另存为test2.php

php yakpro-po.php test.php -o test2.php

混淆后的代码：

常见命令

将混淆后的代码显示在控制台

php yakpro-po.php PHP源文件

将混淆后的代码另存为目标文件

php yakpro-po.php PHP源文件 -o PHP目标文件

对目录下的PHP文件进行混淆，并且另存为其它目标文件夹下

php yakpro-po.php 源文件夹 -o 目标文件夹
