Laravel 5: Retrieving Object Values With object_get

By John Koster

The object_get allows developers to retrieve properties from a given $object using dot notation. This is useful in situations where it can not be guaranteed that a provided object will have a given property, identified by the given $key.

#Signature

The signature of the object_get function is:

1function object_get(

2    $object,

3    $key,

4    $default = null

5);

#Example Use

The following sample class structure will be used in the following examples:

1$sampleObject             = new stdClass;

2$sampleObject->department = new stdClass;

3

4$sampleObject->department->name = 'Marketing';

The department name can be retrieved like so:

1$departmentName = object_get(

2                    $sampleObject,

3                    'department.name'

4                  );

The value of $departmentName would then be Marketing.

Attempting to retrieve the department's address would return NULL:

1// NULL

2$departmentAddress = object_get(

3                        $sampleObject,

4                        'department.address'

5                     );

Or a different $default value can be supplied:

1// `No Address`

2$departmentAddress = object_get(

3                        $sampleObject,

4                        'department.address',

5                        'No Address'

6                     );
