Getting an Image of The HTML Article with PHP preg_match Function

This case occurs in many blog.

You want to show a brief description of an article along with the image which is contain in it article.

You can see what I mean as shown below;

In that case, you don't need to create a new field contain an image in it. You just need to parse the img tag.

This is the code:

private static function getImageInPost($post_content)

{

    $jum = preg_match_all('/src="([^"]*)"/', $post_content,$matches);

        

    if($jum)

    {

        foreach ($matches as $match) 

        {

            if(strpos($match[0], "src")!== false)

            {

                $res = explode("\"", $match[0]);

                $image = "<img src='".$res[1]."'>";

            }

        }

    }

    else 

    {

        $image = "";

    }

        

    return $image;

}

Above code returning first image in the article.
