Simple example of using PHP to determine whether there are pictures in an article

$url="http://XXXXX/article/012.html";
　$content=file_get_contents($url); //Read the article page source code
　if(preg_match("/img/" ){
　echo "Picture detected";
　}else{
　echo "Picture not found";
}

But to be honest, this method of judgment is too far-fetched
