Extracting Code From HTML

[glenelkins]

I have a project where as i have to get some HTML code and take out an image from <img src> tag.
Now i get the file in the following way:

[code]
<?php
    $prods = "http://1564.tchosts3.net/TEMPLATES/Template2/product.asp?intProdID=SVFUJ-879133-001";
    $data = file($prods);
                foreach ($data as $dt) {
        $content=htmlentities($dt);
        echo nl2br($content);
    }
    
?>
[/code]

How do i check each of these lines in the loop to find the <img src=> tag, then to return only the text (filename of image) between the "".
