MgdSchema in PHP
The features described in this part of documentation are still in experimental state and may change in future Midgard releases.
MgdSchema classes are registered as internal PHP classes with default properties set. To make new object instances follow the PHP documentation. The list of loaded MgdSchema types is available in the $_MIDGARD superglobal.
Since Midgard 1.8 every MgdSchema object provides midgard_metadata object.
The Midgard Reflection Property API is available for midgard-php developers.
To query MgdSchema objects stored in the Midgard database, use the Query Builder.
