Install grpc for correct php version

Install PHP version to your ubuntu

<code>sudo add-apt-repository -y ppa:ondrej/php
sudo apt update
sudo apt install php7.3</code>

In case, you have many version of PHP, you need to check

<code>which php
php -v
ls -l /usr/bin/php</code>

If you see the php version is not correctly set, you need to set the environment to use correctly before follow the official doc of grpc, let’s switch the php version:

<code># disable previous version
sudo a2dismod php7.4

# enable new version
sudo a2enmod php7.3

# set default alternative 
sudo update-alternatives --set php /usr/bin/php7.3

# global use
sudo update-alternatives --config php

# In case, you have installed other PHP extensions, set them as default as well.

sudo update-alternatives --set phar /usr/bin/phar7.3</code>

Install grpc from pecl

<code># modules of php 7.3 (state your correct version)
sudo apt install php7.3-common php7.3-mysql php7.3-xml php7.3-xmlrpc php7.3-curl php7.3-gd php7.3-imagick php7.3-cli php7.3-dev php7.3-imap php7.3-mbstring php7.3-opcache php7.3-soap php7.3-zip php7.3-intl -y

# module require
sudo apt-get install php-pear phpunit

# if you have previous version of grpc, uninstall it
pecl uninstall grpc

# install grpc base on specific version
pecl -d php_suffix=7.3 install grpc</code>

Thanks to this post, that give me the idea for pecl to select correct version of php we want.

So you will have correct version of grpc as in folder:

• If PHP 7.2, it will be in folder: /usr/lib/php/20170718
• If PHP 7.3, it will be in folder: /usr/lib/php/20180731
• If PHP 7.4, it will be in folder: /usr/lib/php/20190902

You can find my pre-build of some php modules by version at this location.

In case, you need to build from source

<code># Install phpize for the version we want
sudo apt-get install php7.3-dev
sudo apt-get install phpize7.3

# Clone project for correct version
git clone -b v1.31.x https://github.com/grpc/grpc.git

cd ./grpc

phpize7.3

./configure --with-php-config=/usr/bin/php-config7.3

make clean

make

make install
</code>

Build grpc’s reference post from this article.

I’ll update more if anything related to grpc case here.
