/**
 * This script works by loading up PHP extensions and using reflection to pull
 * the functions, classes, and constants out of those extesions. The list of
 * extensions below are ones included with PHP 5.3 source code. The ones
 * commented out depend on an external library being installed, are Unix
 * specific, or just not commonly used.
 *
 * Add, comment, or uncomment to fit your needs or particular PHP installation.
 * Remember that some of these extensions are likely shared extensions and must
 * be enabled in your php.ini file.
 *
 * NOTE: mysqlnd is not included because it exposes no functions, classes, or
 * constants. The pdo_* extensions are not included in the list because they do
 * not expose any functions, classes, or constants themselves. The constants
 * and methods specific to that driver are exposed though the PDO extension
 * itself. The pdo_* extensions must still be enabled (compiled in or loaded as
 * shared) for these constants to show up.
