redeclaration of class error

Question

i have these three files: index.php:

<div class="tweet_bx">
     <form method="post" name="m_gigs" id="m_gigs" enctype="multipart/form-data"  action="index.php">
       <table width="100%" border="0" cellspacing="0" cellpadding="0">
      <tr>
        <td width="17%"><strong>Filter gigs by</strong></td>
        <td class="<?php echo $class1;  ?>" width="8%" align="center" ><a class="cuuuent" href="index.php?gigs=latest" >Latest</a></td>
        <td class="<?php echo $class2;  ?>" width="15%" align="center"><a href="index.php?gigs=popular">Most Popular</a></td>
        <td class="<?php echo $class3;  ?>" width="15%" align="center"><a href="index.php?gigs=rating" >Best Ratings</a></td>

      </tr>
    </table>
    <table>
    <?php
    include('Sql.php');
    $c = new connexion();
    $videos= $c->getVideos();
    for($i=0;$i<sizeof($videos); $i++)
    {
    ?>
    <tr><td colspan = "2"><img src="<?php echo $videos[$i]['image']; ?> " /></td>
         <td><label color="blue"><?php echo $videos[$i]['titre']; ?></label></td>

    </tr>
    <tr>
    <td><label color="blue"><?php echo $videos[$i]['description']; ?></label></td>
    </tr>


    <?php
    }
    ?>

    </table>

    </form>
    </div>

    <div class="tweet_bx">
    <?php





    ?>

    </div>
    </div>
    <?php include('right.php'); ?>
    </div>

the file right.php:

<div class="right_box">
<div class="right_box_center">
<ul>
<?php
include('Sql.php');

$c = new connexion();
$categories = $c->getCategories();
for($i=0;$i<sizeof($categories) ; $i++){


?>
<li><a href="index.php?categorie=<?php  echo $categories[$i]['categorie'];?>"><?php  echo $categories[$i]['categorie'];?></a> </li>

  <?php
  }
  ?>
   </ul>
   </div>
<img align="middle" src="images/img.jpg" />
<a href="javascript:popup()"> <img align="middle" src="images/invite.jpg" style="padding-left:32px;" /></a>

</div>

and finally the file sql.php:

<?php

i have this error : Fatal error: Cannot redeclare class connexion in /home/a1638637/public_html/Sql.php on line 2 . but i didn't redeclare the class connexion!!
i think that the problem is in the right.php file because:

• the right part doesn't work
• the error appears there
  to fix this error i need to know
• what is the error?
• how can i fix it?

Answer 1

You need to use require_once instead of include. The SQl.php file is read and parsed twice and therefore it tries to redeclare an already declared class. With require_once this won't happen.
