The result of repeated installation of php on centos7 cannot be uninstalled.

After centos7 was repeatedly installed with php, it was finally impossible to uninstall and install php. after that, some yum install php-pdo php-zip files were excerpted on the Internet. as a result, php cannot be uninstalled or reinstalled.
If you use yum install php, the system prompts that the installation is complete. However, php-v prompts that the error does not exist.

The entire process:

Point the bin in the php installation directory to ln xx/usr/bin.

You can try to uninstall it like this:

Rpm-qa | grep phprpm-e [package output above]

If yum is installed, you can uninstall yum and compile a final php command to make a soft connection.
