I have a laravel project that uses firebase and I am not able to install PECL for php7.3. I tried this https://cloud.google.com/php/grpc. When I tried the following command
sudo apt-get install autoconf zlib1g-dev php-dev php-pear
it doesn't install Packages for 7.3 but for 8.0 which is not my requirement. I also tried.
sudo apt-get install autoconf zlib1g-dev php7.3-dev php7.3-pear
But it says it cannot locate the package for 7.3 (E: Unable to locate package php7.3-pear)
Ubuntu 20.04 main repositories support PHP 7.4.
To install 7.3, you will need to use a different source, such as the popular PPA by Ondřej Surý.
