DevOps, CI/CD and Automation

Hi
I have PHP installed on one linux server and developers are using it already. I have been given the task to get the oci8 (oracle connectivity) done on this same server. I can not do the reinstall of whole PHP again. During the install of OCI extention I got many errors for missing PEAR files.
So I went through the PEAR document and found "php go-pear.php" command to install the PEAR package. This command fails with below error.

download of http://pear.php.net/get/PEAR?uncompress=yes failed: Failed to parse address "" (0)

The problem is this Linux box does not have direct internet connectivity so I had to download all the required packages as per go-pear.php on my local machine and I am FTPing them to this linux box. I have kept the "PEAR-1.8.1.tar" file in the same directory where go-pear.php file exists but still the above command tries to download it from internet.
Could you please tell me how can I overcome this problem. Please let me know if there are any RPM's that I can use to install PEAR rather that "php go-pear.php" command.

Thanks
Shelly
