PHP7 代码的加密扩展 安装 编译前先修改 core.h : /* 这里定制你的加密特征头，不限长度，十六进制哦 */ const u_char tonyenc_header[] = { 0x66, 0x88, 0xff, 0x4f, 0x68, 0x86, 0x00, 0x56, 0x11, 0x16, 0x16, 0x18, }; /* 这里指定密钥，设置长一些更安全 */ const u_char tonyenc_key[] = { 0x9f, 0x49, 0x52, 0x00, 0x58, 0x9f, 0xff, 0x21, 0x3e, 0xfe, 0xea, 0xfa, 0xa6, 0x33, 0xf3, 0xc6, }; Linux、macOS 编译 git clone https://github.com/lihancong/tonyenc.git cd tonyenc phpize ./configure make 将编译好的文件 modules/tonyenc.so 加入到配置项 extension=tonyenc.so ，重启 PHP 服务 在 Windows 上编译 已编译了以下模块，可供测试（需要 VC14 运行库）: # php7.0 64位 线程安全版 php_tonyenc_php70_ts_VC14_x64.dll # php7.0 64位 线程非安全版 php_tonyenc_php70_nts_VC14_x64.dll 加密 代码中的 tonyenc.php 是加密工具: php tonyenc.php example.php dir/ 这样即可加密 example.php 和 dir 目录下的所有 php 文件，PHP 在运行它们时会自动解密
