找出使用PHP的OpenSSL和GnuPG的位置？

Question

Is there a cross-platform compliant way of finding out the path to the main executables of OpenSSL and GnuPG? Obviously this would be null if the software was not installed or detected.

Answer 1

您可以通过PATH_SEPARATOR炸开$_ENV['PATH']并在每个路径（类似于GunPG）中查找openssl或openssl.exe （在Windows上）。
