I have a problem with building the package for PHP 7.3 from git. At the moment I am using Ubuntu 16.04 with utdatet php 7.0.x. (It's impossible to upgrade Ubuntu 16.04 to 18.04 at my VPS, because it crashes at boot. I only have Virtuozzo to debug and I can't find the point where it crashes, so upgrading to 18.04 isn't an option yet.)

My steps so far:

I have installed all programs for build, (git, build essential, libtool, bison and re2c).

I cloned the git from GitHub with:

git clone https://github.com/php/php-src.git 

Then I selected the branch I want:

git checkout PHP-7.3 

Then I ran:

./buildconf

What is the next step?

I need the following packages:

  php7.3

  libapache2-mod-php7.3

  php7.3-mysql

  mysql-server

I didn't search for a PPA, because I wanted to do it on my own in order to learn by doing it.

1. 
   

   Install dependencies.

   
   
   

   sudo apt install autoconf automake bison build-essential curl flex 
   
     libtool libssl-dev libcurl4-openssl-dev libxml2-dev libreadline7 
   
     libreadline-dev libsqlite3-dev libzip-dev libzip4 nginx openssl 
   
     pkg-config re2c sqlite3 zlib1g-dev
   
   

   
   
   

   So you don't overwrite any existing PHP installs on your system, install PHP in your home directory. Create a directory for the PHP binaries.

   
   
   

   mkdir -p ~/bin/php7-latest/
   
   

   
   



2. Download the PHP 7.3 from GitHub, decompress it, then change directories using cd to the new directory. You can also download PHP 7.3 from php.net/downloads.php and the installation instructions are exactly the same. Ordinarily this would be the preferred way of downloading PHP 7.3, but I'm using PHP 7.3 from https://github.com/php/ in this answer instead in order to match the PHP 7.3 archive that is asked about in the question.



3. 
   

   Configure PHP. Remove any options you don't need (like MySQL or Postgres (--with-pdo-pgsql))

   
   
   

   ./configure --prefix=$HOME/bin/php-latest 
   
       --enable-mysqlnd 
   
       --with-pdo-mysql 
   
       --with-pdo-mysql=mysqlnd 
   
       --with-pdo-pgsql=/usr/bin/pg_config 
   
       --enable-bcmath 
   
       --enable-fpm 
   
       --with-fpm-user=www-data 
   
       --with-fpm-group=www-data 
   
       --enable-mbstring 
   
       --enable-phpdbg 
   
       --enable-shmop 
   
       --enable-sockets 
   
       --enable-sysvmsg 
   
       --enable-sysvsem 
   
       --enable-sysvshm 
   
       --enable-zip 
   
       --with-libzip=/usr/lib/x86_64-linux-gnu 
   
       --with-zlib 
   
       --with-curl 
   
       --with-pear 
   
       --with-openssl 
   
       --enable-pcntl 
   
       --with-readline
   
   

   
   
   

   Probably you won't need to remove any of the options except for --with-pdo-pgsql=/usr/bin/pg_config if PostgreSQL isn't installed. If you don't remove an option that is specific to a package that isn't installed, then this command will return an error message that tells you what option must be removed so that the command will run successfully.

   
   


4. 
   

   Compile the binaries:

   
   
   

   make # wait until make is finished
   
   make install
   
   

   
   


5. 
   

   Copy the PHP.ini file to the install directory

   
   
   

   cp php.ini-development ~/bin/php-latest/lib/
   
   

   
   


6. 
   

   Rename two files.

   
   
   

   cd ~/bin/php-latest/etc/  
   
   mv php-fpm.conf.default php-fpm.conf
   
   mv php-fpm.d/www.conf.default php-fpm.d/www.conf
   
   

   
   


7. 
   

   Create symbolic links for your for your binary file.

   
   
   

   cd ~/bin
   
   ln -s php-latest/bin/php php
   
   ln -s php-latest/bin/php-cgi php-cgi
   
   ln -s php-latest/bin/php-config php-config
   
   ln -s php-latest/bin/phpize phpize
   
   ln -s php-latest/bin/phar.phar phar
   
   ln -s php-latest/bin/pear pear
   
   ln -s php-latest/bin/phpdbg phpdbg
   
   ln -s php-latest/sbin/php-fpm php-fpm
   
   

   
   


8. 
   

   Link your local PHP to the php command. You will need to logout then log back in for php to switch to the local version instead of the installed version from the default Ubuntu repositories.

   
   
   

   # add this to .bashrc
   
   if [ -d "$HOME/bin" ] ; then
   
     PATH="$HOME/bin:$PATH"
   
   fi
   
   

   
   


9. 
   

   Start PHP-FPM

   
   
   

   sudo ~/bin/php-latest/sbin/php-fpm  
   
   

   
   
   

   If you run the above command as normal user without sudo, it will show the following notices:

   
   
   

   NOTICE: [pool www] 'user' directive is ignored when FPM is not running as root.    
   
   NOTICE: [pool www] 'group' directive is ignored when FPM is not running as root.
