php-bypass

High-risk offensive security skill. Its stated purpose is exploitation: bypassing PHP hardening after webshell access to regain command execution and read restricted files. No strong malware/exfil endpoint evidence is present, but the capability set is fundamentally dangerous and disproportionate for general AI-agent use.

该代码文本明确包含多种恶意代码执行、限制绕过、敏感文件读取和潜在数据窃取技术。若这些示例被包含在可安装或可执行的软件包中，应视为高风险恶意内容并阻止使用。部分方法依赖特定旧版本、扩展或系统配置，但方法 A、D、F 等在满足条件时可直接导致任意命令执行。

该片段不是正常依赖库代码，而是关于 OPcache 投毒、SQL 注入文件写入和多态上传绕过的攻击性技术说明。所述技术可导致任意 PHP 代码执行，安全风险很高；但片段本身未包含实际恶意载荷或明确的数据窃取行为。

The code is exploit-oriented and provides techniques for bypassing PHP open_basedir restrictions, enumerating restricted directories, manipulating symlinks, and reading sensitive files. It does not itself show package-installation malware or network exfiltration, but executing it in a PHP environment can cause unauthorized filesystem disclosure and modification. It should not be used in production or trusted as application code.
