php - array element removed twice -


i have problem delete element in array. every time pass delete procedure, array has reduced something. don't know in line element removed. please me check sample code.

<?php if ($_request['act'] == 'add') {   // add procedure }  if ($_request['act'] == 'del') {   // del procedure   array_splice($_session['items'], $_get['id'], 1); } ?>  <table>   <tr>     <td>no.</td>     <td>content</td>     <td>del?</td>   </tr>   <?php   $j = count($_session['items']);    for($i = 0; $i < $j; $i++) {   ?>   <tr>    <td><?php echo $i + 1; ?>    <td><?php echo $_session['items'][$i]; ?>    <td><a href=<?php echo $_server['php_self']; ?>?act=del&id=<?php echo $i; ?>>del</a>   </tr>   <?php   }   ?> </table> ?>

i have write mark inside del procedure check if condition passed twice, it's echo once.

fyi, not real code. code has multi dimension array. think code reflect real condition.

thanks before.
