昨晚我收到一个奇怪的 php 错误日志。我以前从未在我的服务器上看到过这个，我不知道这意味着什么。
如果您知道的话我将非常感激。

guess.php 是什么？为什么我会得到错误？
谢谢
答案1
该文件Guess.php属于 PHP PEAR 模块 OS_Guess，用于检索有关当前操作系统的信息
您收到的消息告诉您：
popen() has been disabled for security reasons in /usr/lib/php/OS/Guess.php on line 247
popen() 用于打开与另一个进程的通信，出于安全考虑，许多设置中都禁用了该函数。您收到的其他错误是由于 popen() 失败而导致的后续错误。
查看php.net/popen了解有关此功能的更多详细信息。
