Retrieve all attributes from the shortcodes tag.
Syntax Syntax
Description Description
The attributes list has the attribute name as the key and the value of the attribute as the value in the key/value pair. This allows for easier retrieval of the attributes, since all attributes have to be known.
Parameters Parameters
- $text
-
(Required)
Return Return
(array|string) List of attribute values. Returns empty array if trim( $text ) == '""'. Returns empty string if trim( $text ) == ''. All other matches are checked for not empty().
