无法在WP网站上显示Wordpress版本？

Question

I want to display my Wordpress version on an external website, the below code used to work, however it's not anymore.

I cannot

<?
//get the WordPress homepage 
$wp_homepage=file_get_contents('http://wordpress.org'); 

//find start point of the version 
$version_start=strpos($wp_homepage,'Download&nbsp;WordPress&nbsp;');
if($version_start===false) 
{ 
    die('4.1.1'); 
} 
//get rid of the download WordPress part 
$version_start+=29; 

//find end point of version 
$version_end=strpos($wp_homepage,'</a>',$version_start); 

//find the version stated 
$wp_version=substr($wp_homepage,$version_start,$version_end-$version_start); 
?>

I don't understand why it's not working anymore.

Maybe there is a better way as well?

Thanks

Edit: nevermind seemed the code was outdated it only needed
