Error when installing php extensions CENTOS7

[Neutrideo]

Hello, i am installing some extensions on php, i have centos7 installed, any help?

php72w-common conflicts with php-common-5.4.16-43.el7_4.x86_64 You could try using --skip-broken to work around the problem

When i do this,

First search which old php packages are still installed on your machine :

yum list installed | grep php | grep 5.4

Then remove the old packages (for instance php-commom-5.4 .)

yum remove php-common-5.4

Then install the extensions again

I get this,

Loaded plugins: fastestmirror No Match for argument: php-common-5.4 No Packages marked for removal [Gamepanel@ip164 ~]$
