PHP使用Regex查找子串字符串

I have a web page source code that I want to use in my project. I want to use an image link in this code. So, I want to reach this link using regex in PHP.

That's it:

img src="http://imagelinkhere.com" class="image"

There is only one line like this. My logic is to get the string between

="

and

" class="image"

characters.

How can I do that with REGEX? Thank you very much.

    Don't use Regex for HTML .. try DomDocument

    $html = '<html><img src="http://imagelinkhere.com" class="image" /></html>';
    
    $dom = new DOMDocument();
    $dom->loadHTML($html);
    $img = $dom->getElementsByTagName("img");
    
    foreach ( $img as $v ) {
        if ($v->getAttribute("class") == "image")
            print($v->getAttribute("src"));
    }
    

    Output

    http://imagelinkhere.com
