php-gd installed but fails to function in centos 7 (php 7.3 version)

I am trying to install moodle but it shows php-gd extension is missing/should be enabled.
However the gd is already installed and latest, and when I command php -v I get the following error as indicated below. 

PHP Warning:  PHP Startup: Unable to load dynamic library 'gd.so' (tried: /usr/lib64/php/modules/gd.so (/lib64/libraqm.so.0: undefined symbol: hb_ft_font_set_load_flags), /usr/lib64/php/modules/gd.so.so (/usr/lib64/php/modules/gd.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

I did a lot of editing but I could not find a single solution. Please help

    Run:

    yum install libraqm-devel

    [root@* ~]# yum provides '*/libraqm.so*'
Repository epel is listed more than once in the configuration
libraqm-0.7.0-4.el7.x86_64 : Complex Textlayout Library
Repo        : epel
Matched from:
Filename    : /usr/lib64/libraqm.so.0.700.0
Filename    : /usr/lib64/libraqm.so.0



libraqm-devel-0.7.0-4.el7.x86_64 : Complex Textlayout Library
Repo        : epel

Filename    : /usr/lib64/libraqm.so


[root@* ~]# ll /usr/lib64/libraqm.so*

    libraqm.so provided by libraqm-devel.

    Install libraqm-devel will also install freetype and harfbuzz, which provide hb_ft_font_set_load_flags.

    I had the same problem:

    # php --version
PHP Warning:  PHP Startup: Unable to load dynamic library 'gd' (tried: /usr/lib64/php/modules/gd (/usr/lib64/php/modules/gd: cannot open shared object file: No such file or directory), /usr/lib64/php/modules/gd.so (/lib64/libraqm.so.0: undefined symbol: hb_ft_font_set_load_flags)) in Unknown on line 0

    A quick search in google told me that hb_ft_font_set_load_flags comes from HarfBuzz (https://harfbuzz.github.io/harfbuzz-hb-ft.html).

    I installed it with yum install harfbuzz, and after that the warning is gone:
