如何从 PHP 中的字符串位置排除图像扩展名

我想替换从example.com到sample.com的所有字符串值，不包括图像扩展名.png、.jpeg、.jpg等.

$body = ' www.example.com, example.com, example.com/hello.html, example.com/logo.png, example.com/yourbaby.php , example.com/newimage.jpg, www.example.com/newimage.jpg';

//values    
$oldomain = ['example.com','www.']; 
$newdomain= ['sample.com', ''];
$excludeextension = [".png", ".jpg", ".jpeg"];

//Replace    
$body = str_replace($olddomain, $newdomain, $body);
$body = str_replace($excludeextension, '', $body);

//output    
 echo $body; 

Output i am looking for :个
