echo pdo_mysql_get_client_info();
$imagick = new \Imagick(); echo $imagick->getVersion();This will output something like "ImageMagick 6.8.9-9 Q16 x86_64 2018-10-19 http://www.imagemagick.org". In this example, the Imagick library implements the get_version module as a method of its object-oriented interface. In both cases, we are using the get_version module to retrieve the version number of a specific package or library, which can be useful for logging, checking for updates, or debugging. Package/library determination: The package/library being used in each example is clear from the function or method name being called. In the first example, we are using the PDO library and specifically the pdo_mysql_get_client_info() function. In the second example, we are using the Imagick image manipulation library and specifically the Imagick->getVersion() method.
