## Installation

This » PECL extension is not bundled with PHP.

An example installation procedure on Ubuntu 18.04 with PHP 7.2:

    // Dependencies
    $ apt install build-essential libprotobuf-dev libboost-dev openssl protobuf-compiler

    // PHP with the desired extensions; php7.2-dev is required to compile
    $ apt install php7.2-cli php7.2-dev php7.2-mysql php7.2-pdo php7.2-xml

    // Compile the extension
    $ pecl install mysql_xdevapi

The pecl install command does not enable PHP extensions (by default) and enabling PHP extensions can be done in several ways. Another PHP 7.2 on Ubuntu 18.04 example:

    // Create its own ini file
    $ echo "extension=mysql_xdevapi.so" > /etc/php/7.2/mods-available/mysql_xdevapi.ini

    // Use the 'phpenmod' command (note: it's Debian/Ubuntu specific)
    $ phpenmod -v 7.2 -s ALL mysql_xdevapi

    // A 'phpenmod' alternative is to manually symlink it
    // $ ln -s /etc/php/7.2/mods-available/mysql_xdevapi.ini /etc/php/7.2/cli/conf.d/20-mysql_xdevapi.ini

    // Let's see which MySQL extensions are enabled now
    $ php -m |grep mysql

    mysql_xdevapi
    mysqli
    mysqlnd
    pdo_mysql
