too long

I am trying to install PHP OPCACHE on my Amazon Linux EC2 instance but I am getting some errors related to conflict. The version of PHP running on my EC2 is PHP Version 5.3.29. More details can be seen here Info

I am trying to install it via SSH using Putty. I am using the following command,

sudo yum install -y php54-pecl-apc

OR

sudo yum install php55-opcache

I still get the error. Error enter image description hereHow can I install OPCACHE? Am I doing any other mistake?
