How to trim String text in php

For example we have text

<strong>
                     
                         
                            The Times
                          
                        NY
                     
                </strong>

 But good result need be

<strong>The Times NY</strong>

 I make regexp in php

function trim_text($str)                             
{                                                    
    return trim(preg_replace('/\s{2,}/', ' ', $str));                                                 
}
