将MySQL数据格式化为PHP中的下一列的最简单方法

Question

I have my data being output to a span currently... this is how it looks:

Now, when i remove the span and place a div there i am given this output:

This is desired, but I want to set a height to my page and have the data show up in as little as 3 columns. How would I do this? I have searched everywhere online but can't seem to find anything that shows a solution.

I did read that some use javascript for the format but i am still clueless on even this option.

My desired output would look like this:

Answer 1

If you know how many items you want in a column then you can seperate them out into individual divs and then float those divs to the left to get them to be next to each other.

<div style='float:left'>
    //Items go here
</div>
<div style='float:left'>
    //Items go here
</div>

etc. If you figure out how many items your query returned, say using mysql_num_rows() and divide by 3 you can tell how many to put in each column. Also be sure to clear the floats afterwards, so like this:

<div style="clear:both"></div>

Sometimes this is necessary as there will be random issues if this is not put there.

Answer 2

What you are describing can be solved with styling only. You have several divs that must be displayed in columns. The easiest way is floating them to the left, and setting the width for 1/3 of the parent. If you want 4 columns, set the with to 1/4 of the parent, and so on.

<div class='sqlResult' style="float:left;width:33%;">
<a href='#'>$key</a>
</div>

Also as other answers mentioned, don't use duplicated ids. Always use classes. If you need to target each div individually, give it a unique id, such as "category_1", "category_2", and so on.

Answer 3

This should work

<table><tr>
<?php $count=0; $total=mysqli_stmt_num_rows($sql)-1; $idxcount=0; $limit=10; while($row = mysqli_fetch_array($sql)): $key = $row['Keyword_Name']; ?>
        <?php if($count == 0){ echo '<td>';} ?>
        <span>
                <a href="<?php echo $key; ?>" id="category"><?php echo $key; ?></a>
        </span>
        <?php if($total == $idxcount): ?>
                </td>
        <?php elseif($count == $limit): ?>
                </td>
        <?php $count=0; else: $count++; ?>

        <?php  endif; $idxcount++; ?>

<?php endwhile; ?>
</tr></table>
