shell_exec nmap php无法与其他版本一起使用

Question

I have a very strange problem. I'm trying to make a program that executes shell_exec() in PHP with NMAP.

The problem comes when I put shell_exec("nmap --version") , because it returns me version 4.11 , but when I put it directly on shell, it returns me version 7.01 .

使用shell_exec时，应始终使用可执行文件的完整路径。
