Different result in phpMyAdmin and php

Question

In phpMyAdmin, I am writing

SELECT `class` FROM `teachers` WHERE `var1`=3;

I can give results. The Results are 5,6,7,8,9,10. I am Trying this code in Sublimetext3. code is like this :

<tr>            
    <?php 

    $classlistdata  = $db->getrows("SELECT `class` FROM `teachers` WHERE `var1`=3; ");
    foreach ($classlistdata as $ndcld) {     

    ?>
    <td height="25" colspan="3" ><span class="admin"><?php  echo ($ndcld); ?></span></td>

    <?php } ?>
</tr>

this code writing 6 times "array" . How can I fix it. I am new PHP. thanks for your answer.

Answer 1

您应该使用echo $ndcld['class'];

Answer 2

I don't know whats behind the getrows method, but likely its just an normal SQL query since you get arrays. Well, in your case, ndcld is an array. An array containing all the queried attributes as an array key.

Change your code to:

$classlistdata  = $db->getrows("SELECT `class` FROM `teachers` WHERE `var1`=3; ");
foreach ($classlistdata as $ndcld) {     

?>
<td height="25" colspan="3" ><span class="admin"><?php echo $ndcld["class"]; ?></span></td>

<?php } ?>

That should do the job ;)
