php - Get outerHTML from a website and put it into a string. I'm lost -

there (dynamic) websites source code not equal outerhtml of site. example, source code of site of interest is:

            <table>                 <tr>                     <td class="tname-home logo-enable">                         <span class="tname">                             <span style="display: none" class="dw-icon ico">&nbsp;                             </span>                             <a href="#" onclick="window.open('/team/unics-kazan/rtwgehhr'); return false;">unics kazan</a>                         </span>                      </td>                      <td class="current-result">                         <span class="scoreboard-divider">-                         </span>                      </td>                      <td class="tname-away logo-enable">                         <span class="tname"><a href="#" onclick="window.open('/team/maccabi-tel-aviv/nluro05b'); return false;">maccabi tel aviv</a>                             <span style="display: none" class="dw-icon ico">&nbsp;</span>                         </span>                      </td>                 </tr>              </table> 

as can see corresponds "live score" of game. in code, nonetheless, score doesn't appear. "-" divides score of local team , away team.

if have @ outerhtml of same element, find this:

           <table>                         <tr>                <td class="tname-home logo-enable">                     <span class="tname">                         <span style="display: none" class="dw-icon ico" title="advancing next round">&nbsp;                         </span>                         <a href="#" onclick="window.open('/team/unics-kazan/rtwgehhr'); return false;">unics kazan</a>                     </span>                </td>                <td class="current-result">                   <span class="r">                     <span class="scoreboard">61                     </span>                     <span class="scoreboard-divider">-                     </span>                     <span class="scoreboard">63                     </span>                   </span>                 </td>                 <td class="tname-away logo-enable">                     <span class="tname"><a href="#" onclick="window.open('/team/maccabi-tel-aviv/nluro05b'); return false;">maccabi tel aviv</a>                         <span style="display: none" class="dw-icon ico" title="advancing next round">&nbsp;</span>                      </span>                 </td>              </tr>            </table> 

note code similar, not equal, now, actual score visible (61-63 @ moment).

the question how can store outerhtml of website php string, can work it. function:

file_get_contents("www.website.com") 

would capture first code, has no score on it...

should need other explanation, please let me know. important me solve issue. thank you!
