// This will occur when the comment is posted functionplc_comment_post( $incoming_comment) { // convert everything in a comment to display literally $incoming_comment['comment_content'] = htmlspecialchars($incoming_comment['comment_content']); // the one exception is single quotes, which cannot be #039; because WordPress marks it as spam $incoming_comment['comment_content'] = str_replace( "'", ''', $incoming_comment['comment_content'] ); return( $incoming_comment); } // This will occur before a comment is displayed functionplc_comment_display( $comment_to_display) { // Put the single quotes back in $comment_to_display= str_replace( ''', "'", $comment_to_display); return$comment_to_display;}

The core idea of PHP combining AI for video content analysis is to let PHP serve as the backend "glue", first upload video to cloud storage, and then call AI services (such as Google CloudVideoAI, etc.) for asynchronous analysis; 2. PHP parses the JSON results, extract people, objects, scenes, voice and other information to generate intelligent tags and store them in the database; 3. The advantage is to use PHP's mature web ecosystem to quickly integrate AI capabilities, which is suitable for projects with existing PHP systems to efficiently implement; 4. Common challenges include large file processing (directly transmitted to cloud storage with pre-signed URLs), asynchronous tasks (introducing message queues), cost control (on-demand analysis, budget monitoring) and result optimization (label standardization); 5. Smart tags significantly improve visual
