<p class="para">
This <a href="http://pecl.php.net/" class="link external">» PECL</a> extension
is not bundled with PHP.
</p>
<p class="para">
An example installation procedure on Ubuntu 18.04 with PHP 7.2:
</p>
<div class="example-contents">
<div class="cdata"><pre>
// 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
</pre></div>
</div>
<p class="para">
The <em>pecl install</em> 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:
</p>
<div class="example-contents">
<div class="cdata"><pre>
// 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
</pre></div>
</div>
