| serialize_block_attributes( $block_attributes ) X-Ref |
| Given an array of attributes, returns a string in the serialized attributes format prepared for post content. The serialized result is a JSON-encoded string, with unicode escape sequence substitution for characters which might otherwise interfere with embedding the result in an HTML comment.

| excerpt_remove_blocks( $content ) X-Ref |
| Parses blocks out of a content string, and renders those appropriate for the excerpt. As the excerpt should be a small string of text relevant to the full post content, this function renders the blocks that are most likely to contain such text. since: 5.0.0 return: string The parsed and filtered content. param: string $content The content to parse. |
