I've lunched a fresh instance from the AWS -> EC2 console panel. After that when I logged into the instance via SSH and executed the following line: (note I executed first the sudo yum update before executed the below code)
sudo yum install gcc make httpd php56-common php56-cli php-pear php-devel git ImageMagick-devel
I'm getting the following error message at the end.
Error: php56-common conflicts with php-common-5.3.29-1.7.amzn1.x86_64
Error: php56-cli conflicts with php-cli-5.3.29-1.7.amzn1.x86_64
Error: php56-process conflicts with php-process-5.3.29-1.7.amzn1.x86_64
Error: php56-xml conflicts with php-xml-5.3.29-1.7.amzn1.x86_64
From the error message I understand that lower PHP version is conflicting with new PHP version, but what I don't understand is I didn't even install the php 5.3 but some how it's there in the new instance.

Some instances come with more packages installed than others. It may be that whoever created this AMI they assumed people would want PHP pre-installed on it, or that some other package that they wanted to have preinstalled on it required PHP as a dependency.
