PHP 5.6 Extension Cannot Be Installed

I try to install PHP 5.6 extension like mysql, mysqlnd, etc. Nothing happen.

Example, when i install mysqlnd show like this :
Loaded plugins: fastestmirror, priorities
Loading mirror speeds from cached hostfile

  • epel: epel.dionipe.id
  • extras: centos.biz.net.id
  • updates: centos.biz.net.id

    You could try using --skip-broken to work around the problem
    You could try running: rpm -Va --nofiles --nodigest

How can i installed ?

→ Processing Conflict: lsphp56-mysql56-5.6.29-1.el7.centos.x86_64 conflicts lsphp56-mysql

So, i have to remove lsphp56-mysql56-5.6.29-1.el7.centos.x86_64 before and try to install lsphp56-mysql again ?
