Thank you all the same

Thank you very much for your guidance. ACF seems to be set in every article. I only know the custom fields of ACF. I didn’t understand the description document by checking the pictures, but I found a lot of code and pieced together the following function fragments. If you see anything that needs to be improved, please help me.

function hui_get_thumbnail( $single=true, $must=true ) {
    global $post;
    $html = '';
    
        $content = $post->post_content;
        preg_match_all('/<img.*?(?: |\\t|\\r|\\n)?src=[\'"]?(.+?)[\'"]?(?:(?: |\\t|\\r|\\n)+.*?)?>/sim', $content, $strResult, PREG_PATTERN_ORDER);
        $images = $strResult[1];
        $counter = count($strResult[1]);
        $i = 0;
        foreach($images as $src){
            $i++;
            $src2 = wp_get_attachment_image_src(hui_get_attachment_id_from_src($src), 'thumbnail');
            $src2 = $src2[0];
            if( !$src2 && true ){
                $src = $src;
            }else{
                $src = $src2;
            }
            $item = sprintf('<li class="item"><img src="%s" alt="' . get_the_title() . '" /></li>', $src);
			 $item2 = sprintf('<li class="fist-image"><img src="%s" alt="' . get_the_title() . '" /></li>', $src);
            if( $single){
                return $item;
                break;
            }
            $html .= $item;
	if($counter < 4 ){
 return $item2;
                break;
}
            if(
                ($counter >= 4 && $i >= 4) ||
                ($counter > 0 && $counter < 4 && $i >=$strResult[1][0])
            ){
                break;
            }
        }
  
    return $html;
}
function hui_get_attachment_id_from_src ($link) {
    global $wpdb;
    $link = preg_replace('/-\d+x\d+(?=\.(jpg|jpeg|png|gif)$)/i', '', $link);
    return $wpdb->get_var("SELECT ID FROM {$wpdb->posts} WHERE guid='$link'");
