Yum install php v5.4 packages while I have installed php 7

manpreet Best Answer 3 years ago

I have installed PHP version 7 on my centOs.

Now I got an error says:

undefined function mb_internal_encoding()

So I decided to install php-mbstring (using yum install php-mbstring) but I face the following error:

Error: php70u-common conflicts with php-common-5.4.16-43.el7_4.x86_64

Error: php70u-json conflicts with php-common-5.4.16-43.el7_4.x86_64

But now when I install php-mbstring, it wants to install php-mbstring version 5.4.

How can I tell yum to download latest versions of php extensions and packages?

You've both php5 and php7 installed in your system which is creating conflict. If you're using php7only then remove another version using

yum remove php-*

Install the necessary php7 packages only after complet removal of older version. If you need multiple versions of php to be installed, please google for particular procedure. It's not very simple.

Note While removing softwares with wildcards remember to check what yum is going to remove before proceeding further.
