使用PHP从网页获取脚本内容

I want to get the specific content from script tags from a web page.
Here is HTML page.

<html>
    <head>
        <title></title>
       <script>
         //some other srcipt code
       </script>
    </head>
<body>
       <script>
         //some other srcipt code
       </script>
    <!-- some other html code -->
<script>
var abc = {"asld":"asdjk","thisone":"https:\/\/www.example.com\/$N.jpg|#1000#M$M#JSuL8|1000#M$M#fW4EC0jcOl8kUY_QBZbOASsF8t0","user_gender":"m"};
</script>

</body>
</html>   

I want to get only this value fW4EC0jcOl8kUY_QBZbOASsF8t0 which is in the last attribute of thisone in a script variable var abc.
Can I do this with PHP HTML DOM. If no then how can I do

You can easily get it using the regex

"thisone":".*#(.*)",

Assuming, the webpage is http://example.com,

$data = file_get_contents('http://example.com');
preg_match_all("/\"thisone\":\".*#(.*)\",/", $data, $output);
echo $output[1][0]; // prints fW4EC0jcOl8kUY_QBZbOASsF8t0

Hope that helps!
