How to downgrade PHP from 7.2 to 7.0

Question

I am running CentOS 7.4 and HTTP 2.4.6

I installed PHP 7.2.3

I know need to downgrade to 7.0 (reason is software company initially told me to install latest/stable for PHP and now they tell me 7.2 won't work I need 7.0 -- ugh)

How do I go from 7.2 to 7.0 in PHP?

php -v returns: PHP 7.2.3 (cli) (built: Mar 2 2018 12:41:10) ( NTS )

Solution

You have php installed from remi-php72, and you want php from remi-php70

Try:

yum-config-manager --enable remi-php70
yum-config-manager --disable remi-php72

Then downgrade everything and upgrade again (for noarch package)

yum downgrade php\*
yum update

Or simply (only the 7.2.3 packages)

yum downgrade php-bcmath php-cli php-common php-devel \
  php-gd php-gmp php-imap php-intl php-json php-ldap \
  php-mbstring php-mysqlnd php-odbc  php-pdo php-process \
  php-recode php-soap php-tidy php-xml

Or to remove everything and start new installation

yum remove php\*

Show the output of ˋyum list installed | grep phpˋ. And where did you get those ˋuˋ package names from like ˋphp72uˋ? Also, how did you install v7.2?

Find the package name providing the php command: rpm -qf $(which php)

[FooBee]

BTW, apparently you have added the repositories for EL 6 onto EL 7. This can't work.

yum remove php-common

I wouldn't try to yum downgrade and yum upgrade. That would probably not work. I'd just use yum distro-sync instead.

Ah, indeed, I always forget about distro-sync.... very good idea
