yum install yum-utils yum-config-manager --enable remi-php74
STEP 3 :
Under RHEL 8 and Centos 8
To Install php 7.4:
dnf install php php-opcache php-gd php-curl php-mysqlnd
** you can list all php and install the packages you need.
To upgrade from previous php version to 7.4 :
Now just run this command :
dnf module install php:remi-7.4 dnf update -y
Under RHEL6, 7 and Centos 6, 7

dnf module disable php:remi-5.6 dnf module disable php:remi-7.0 dnf module disable php:remi-7.1 dnf module disable php:remi-7.2 dnf module disable php:remi-7.3
Under RHEL6, 7 and Centos 6, 7
If php upgrade process fails (no update/nothing happens) or you upgraded php previously to 7.0/7.1/7.2/7.3 then you need to run this commands to disable php 5.6/7.0/7.1/7.2/7.3 :
yum-config-manager --disable remi-php56 yum-config-manager --disable remi-php70 yum-config-manager --disable remi-php71 yum-config-manager --disable remi-php72 yum-config-manager --disable remi-php73
