Xml error while installing php from source

php installation error:
configure: error: xml2-config not found. Please check your libxml2 installation

You may get this error even though if your system is having libxml2. So, it could be due to a additional libxml2 module. These can de done by installing libxml2-devel.

yum install libxml2-devel

That’s it. Now you may able to continue the further installation.
