Accessing Wordpress blocks data using parse_blocks()

Having fully accepted Wordpress Gutenberg and made the slow transition over to blocks I will be posting a few things I have learnt on the way.

First up will be to get all blocks added to a post or page using parse_blocks(). Within a post loop:

$blocks = parse_blocks( $post->post_content );
print_r($blocks);

The output of this will be something like:

Array
(
    [0] => Array
        (
            [blockName] => core/paragraph
            [attrs] => Array
        (
          [fontSize] => large
        )
        [innerBlocks] => Array
    (
    )

You can then loop over this array and perform various tasks.

$blocks = parse_blocks( $post->post_content );
foreach( $blocks as $block ) {
  // Do something
}
