May i know how to install php-mbstring. Here are my server version:

OS:
NAME="Red Hat Enterprise Linux Server"
VERSION="7.4 (Maipo)"

PHP:
PHP 7.3.4 (cli) (built: Apr 2 2019 13:48:50) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.4, Copyright (c) 1998-2018 Zend Technologies

I am restricted to connect to the internet. The only way to install php extensions is by downloading rpm. Here are the php extensions installed:

php-gd-7.3.4-1.el7.remi.x86_64
php-7.3.4-1.el7.remi.x86_64
php-sqlsrv-5.6.1-2.el7.remi.7.3.x86_64
php-json-7.3.4-1.el7.remi.x86_64
php-pdo-7.3.4-1.el7.remi.x86_64
php-cli-7.3.4-1.el7.remi.x86_64
php-pdo-dblib-7.3.4-1.el7.remi.x86_64
php-xml-7.3.4-1.el7.remi.x86_64
php-common-7.3.4-1.el7.remi.x86_64
php-soap-7.3.4-1.el7.remi.x86_64
php-pecl-mcrypt-1.0.2-1.el7.remi.7.3.x86_64
php-pgsql-7.3.4-1.el7.remi.x86_64

Kindly point me to the right direction to get the installer for php-mbstring. My application is very dependent from this function. PHP 5.XX works perfectly fine but I need to update my PHP version. Thank you

You obviously need the php-mbstring package.

Please be aware than

  • RHEL 7.4 is outdated and unmaintained, current is 7.7
  • PHP 7.3.4 is outdated and unmaintained, affected by various security issues, including a critical one, current is 7.3.11

BTW, you can download php-mbstring-7.3.4-1.el7.remi.x86_64.rpm from online archive.
