Explanation About the parse_blocks() Function in WordPress
In WordPress, one of the powerful tools for working with content is the function parse_blocks(). This function is used to parse content that is structured with blocks, meaning content that is created with the block editor. By using this function, you can manage complex content that includes multiple blocks in a structured way.
