serialize_block( array $block ): string
Returns the content of a block, including comment delimiters, serializing all attributes from the given parsed block.
Description
This should be used when preparing a block to be saved to post content.
Prefer render_block
when preparing a block for display. Unlike render_block
, this does not evaluate a block’s render_callback
, and will instead preserve the markup as parsed.
Parameters
-
$block
array Required -
A representative array of a single parsed block object. See WP_Block_Parser_Block.
Return
string String of rendered HTML.

A sample code to understand how this works. I am using https://developer.wordpress.org/cli/commands/eval-file/ to execute this.
