Regular expression-solves a PHP regular match pattern?

Grab a page with a datasheet with curl, just get all the cells under TR and use the following method

$content = 内容;preg_match_all('/(.*?)<\/td>/',$content,$res);

But there are two things that can't be matched.

                            内容                                    

And

            未付                                                                                                                    

Don't know why cells with a lot of space and cells with class can't match? Because there is no regular, a pattern can be fully matched out of TD.
There is also a problem with two table on the page. One for various conditions to filter the data, a hold the data, how to match the data only the table?

The line break cannot be matched in single-line mode.
You can use

\s匹配任意的空白符\S匹配任意不是空白符的字符

Extrapolate, match TD with Class.

/
  
   
    
   ([\s\S]+?)<\/td>/
  
   

Match one of the table's, the same extrapolate Ah, first from all the contents of the table into an array.

/
  
   
    
   ([\s\S]+?)<\/table>/
  
   

Then see you want the first few, and then use the above regular match again not good.

Or that sentence, extrapolate Ah!

$pattern = "/
  
   
    
   ([\s\S]*?)<\/td>/";
  
   

I don't think so.
