/**
|
|
* Converts a simpleXML element into an array. Preserves attributes and everything.
|
|
* You can choose to get your elements either flattened, or stored in a custom index that
|
|
* you define.
|
|
* For example, for a given element
|
|
* <field name="someName" type="someType"/>
|
|
* if you choose to flatten attributes, you would get:
|
|
* $array['field']['name'] = 'someName';
|
|
* $array['field']['type'] = 'someType';
|
|
* If you choose not to flatten, you get:
|
|
* $array['field']['@attributes']['name'] = 'someName';
|
|
* _____________________________________
|
|
* Repeating fields are stored in indexed arrays. so for a markup such as:
|
|
* <parent>
|
|
* <child>a</child>
|
|
* <child>b</child>
|
|
* <child>c</child>
|
|
* </parent>
|
|
* you array would be:
|
|
* $array['parent']['child'][0] = 'a';
|
|
* $array['parent']['child'][1] = 'b';
|
|
* ...And so on.
