如何激活标题按钮和列出的按钮？

First of all, apoligise for the messy title, I could not came up with a better one. You will understand the question better in the code. When I click in Private University I can make that button active, but I either want to make active the button Study Opportunity. Thanks.

<li class="dropdown <?php if(basename($_SERVER['SCRIPT_NAME']) == 'study-opportunity.php'){echo 'active'; }else { echo ''; } ?>">
                  <a href="study-opportunity.php" role="button" aria-expanded="false">Study Opportunity<span class="caret"></span></a>
                  <ul class="dropdown-menu" role="menu">
                    <li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'universitetet-me-konkurim.php'){echo 'active'; }else { echo ''; } ?>"><a href="universitetet-me-konkurim.php">Universitetet me Konkurim</a></li>
                    <li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'private-university.php'){echo 'active'; }else { echo ''; } ?>"><a href="private-university.php">Private University</a></li>
                    <li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'studime-jashte-vendit.php'){echo 'active'; }else { echo ''; } ?>"><a href="studime-jashte-vendit.php">Studime Jashte Vendit</a></li>
                    <li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'bursa.php'){echo 'active'; }else { echo ''; } ?>"><a href="bursa.php">Bursa Studimi</a></li>               
                  </ul>
                </li>

You have to check all of the links in the dropdown too:

<li class="dropdown <?php if(basename($_SERVER['SCRIPT_NAME']) == 'study-opportunity.php' || basename($_SERVER['SCRIPT_NAME']) == 'universitetet-me-konkurim.php' || basename($_SERVER['SCRIPT_NAME']) == 'private-university.php' || basename($_SERVER['SCRIPT_NAME']) == 'studime-jashte-vendit.php' || basename($_SERVER['SCRIPT_NAME']) == 'bursa.php'){echo 'active'; }else { echo ''; } ?>">
<a href="study-opportunity.php" role="button" aria-expanded="false">Study Opportunity<span class="caret"></span></a>
    <ul class="dropdown-menu" role="menu">
        <li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'universitetet-me-konkurim.php'){echo 'active'; }else { echo ''; } ?>"><a href="universitetet-me-konkurim.php">Universitetet me Konkurim</a></li>
        <li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'private-university.php'){echo 'active'; }else { echo ''; } ?>"><a href="private-university.php">Private University</a></li>
        <li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'studime-jashte-vendit.php'){echo 'active'; }else { echo ''; } ?>"><a href="studime-jashte-vendit.php">Studime Jashte Vendit</a></li>
        <li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'bursa.php'){echo 'active'; }else { echo ''; } ?>"><a href="bursa.php">Bursa Studimi</a></li>               
    </ul>
</li>
