||
6 | * The parent class for all Elgg Entities. |
||
7 | * |
||
8 | * An \ElggEntity is one of the basic data models in Elgg. |
||
9 | * It is the primary means of storing and retrieving data from the database. |
||
10 | * An \ElggEntity represents one row of the entities table. |
||
11 | * |
||
12 | * The \ElggEntity class handles CRUD operations for the entities table. |
||
13 | * \ElggEntity should always be extended by another class to handle CRUD |
||
14 | * operations on the type-specific table. |
||
15 | * |
||
16 | * \ElggEntity uses magic methods for get and set, so any property that isn't |
||
17 | * declared will be assumed to be metadata and written to the database |
||
18 | * as metadata on the object. All children classes must declare which |
||
19 | * properties are columns of the type table or they will be assumed |
||
20 | * to be metadata. See \ElggObject::initializeAttributes() for examples. |
||
21 | * |
||
22 | * Core supports 4 types of entities: \ElggObject, \ElggUser, \ElggGroup, and \ElggSite. |
||
23 | * |
||
24 | * @tip Plugin authors will want to extend the \ElggObject class, not this class. |
||
25 | * |
||
26 | * @package Elgg.Core |
||
27 | * @subpackage DataModel.Entities |
||
28 | * |
||
29 | * @property string $type object, user, group, or site (read-only after save) |
||
30 | * @property string $subtype Further clarifies the nature of the entity (this should not be read) |
||
31 | * @property-read int $guid The unique identifier for this entity (read only) |
||
32 | * @property int $owner_guid The GUID of the owner of this entity (usually the creator) |
||
33 | * @property int $container_guid The GUID of the entity containing this entity |
||
34 | * @property int $access_id Specifies the visibility level of this entity |
||
35 | * @property int $time_created A UNIX timestamp of when the entity was created |
||
36 | * @property-read int $time_updated A UNIX timestamp of when the entity was last updated (automatically updated on save) |
||
37 | * @property-read int $last_action A UNIX timestamp of when the entity was last acted upon |
||
38 | * @property string $enabled Is this entity enabled ('yes' or 'no') |
||
39 | * |
||
40 | * Metadata (the above are attributes) |

41 | * @property string $location A location of the entity |

The expression
$name of type null|string is loosely compared to true ; this is ambiguous if the string can be empty. You might want to explicitly use !== null instead.
In PHP, under loose comparison (like For '' == false // true
'' == null // true
'ab' == false // false
'ab' == null // false
// It is often better to use strict comparison
'' === false // false
'' === null // false
