Question posted in 
CentOS 7.6
I’ve ran through this same process on 5.x versions and 7.2 without issue, but some pear/pecl steps are failing in 7.4 as I’m attempting an upgrade migration from 7.2 right now.
During the provisioning process I am running a timezonedb upgrade from pecl and hitting an error:
[root@d9471f6a1ab2 /]# pear upgrade -c pecl.php.net timezonedb
downloading timezonedb-2019.3.tgz ...
Starting to download timezonedb-2019.3.tgz (413,166 bytes)
....................................................................................done: 413,166 bytes
5 source files, building
running: phpize
Can't find PHP headers in /usr/include/php
The php-devel package is required for use of this command.
ERROR: `phpize' failed
So naturally I attempt to install the package it asked for php-devel however it attempts to downgrade some of my existing packages back to php5.4!
yum install php-devel
...
Error: php73-cli conflicts with php-cli-5.4.16-46.1.el7_7.x86_64
Error: php73-common conflicts with php-common-5.4.16-46.1.el7_7.x86_64
My normal procedure for building out a php runtime includes installing timezonedb pecl package and upgrading it during the provisioning process. This process hasn’t changed much on all previous PHP upgrades, but I’m having some trouble on php7.4
The full package list is included below, but most importantly, I have the following installed:
php74-php-pear
php74-php-devel
Here is the output of yum list installed php*
[root@d9471f6a1ab2 /]# yum list installed php*

EDIT: Updated Solution
Below is my original solution. However the root issue here is that the remi install for some reason doesn't add anything to the $PATH when yum is used to install the packages.
It installs things into
/opt/remi/php74/and then its up to you to update your environment variables.There is an environment source file left over as a hint on what to do:
In my case I was using docker, so I added to my Dockerfile:
After that, everything works! So the environment variables are all that was needed. You could use rc.local, /etc/environment, etc to update your environment with them.

ORIGINAL SOLUTION:
Ended up resolving with the following:
Ensure we have most recent repos:
Then, at minimum, install
php74-php-pearandphp74-php-devel(I needed to install WAY MORE libs, but I believe these are all that's required)Link the pear that remi installed. Not sure why this didn't take place in the first place:
Then I was able to do what I needed to do:
Worked successfully.
1/
timezonedbextension is NOT useful.RPM packages use the system
tzdata, which is updated separately.2/ you are confused with package names
php74-php-*packages are Software Collections designed for parallelinstallation of multiples verson
php-*packages are simpler to use as single / default versionAs explained in the FAQ, and if you follow the wizard instructions.
3/ don’t need to build from sources
most useful extensions are available as binary packages, see the full list
4/ symlinks and environment
If you really prefer the SCL packages (php74-php-*), you can simply set the environment using the command
As SCL are designed for multiples versions, this allow to switch from one version to another
And if you want to make a collection the default one, you can install the
php74-syspathspackagesBut again, simpler to use the
php-*packages
