PHP表数据显示结果垂直不水平

Question

我真的很沮丧..我真的需要显示这张表的权利。如何设置这个代码来显示表垂直这样的：

1 - 4 - 7

2 - 5 - 8

3 - 6 - 9

而且不喜欢这样的：

1 - 2 - 3 - 4

5 - 6 - 7 - 8

9 - ... E ct

因为我不知道你通过它使用循环和生产表的原始数据结构，我认为它作为一维数组，你要打印的表作为3如你列说，在行动中看到这里有一个PHP Fiddle - 命中运行时执行它 - 这对于任何数组长度工作，只要列是3，行是动态

PHP：更新了命名目的

<?php 
    $table = '<table class="address-labels" width="30%" border="0" cellpadding="0">'; 
    $dataArr = array(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16, 17); 
    $colNum = 3; 
    $rowNum = ceil(count($dataArr)/$colNum); 
    for($i=0; $i < $rowNum; $i++){ 
     $x1 = isset($dataArr[$i]) ? $dataArr[$i] : '-'; 
     $x2 = isset($dataArr[$i + $rowNum]) ? $dataArr[$i + $rowNum] : '-'; 
     $x3 = isset($dataArr[$i + 2 * $rowNum]) ? $dataArr[$i + 2 * $rowNum] : '-'; 
     $table .= '<tr><td>' . $x1 . '</td><td>' . $x2 . '</td><td>' . $x3 . '</td></tr>'; 
    } 
    $table .= '</table>'; 
    echo $table; 

?>

编辑： 现在，如果你想改变列号，就像它设置为5，例如，你需要做到以下几点：

月1日 - 设置$colNum = 5; 2日 - 添加多个变量来保存喜欢的值，*考虑到它是5列：

$x4 = isset($dataArr[$i + 3 * $rowNum]) ? $dataArr[$i + 3 * $rowNum] : '-'; 
$x5 = isset($dataArr[$i + 4 * $rowNum]) ? $dataArr[$i + 4 * $rowNum] : '-'; 

，不要忘记增加乘法器* $rowNum

然后对每个要添加额外的列，你需要添加<td></td>，如：

'<td>' . $x4 . '</td><td>' . '</td><td>' . $x5 . '</td><td>' . '</td>' 

这里的另一个PHP Fiddle表示对上述5列。

试试这个。这是一个在纯PHP

<?php 

$cols = 3; 
$data = range(1,29); 


// classic 
$index = 1; 
foreach($data as $el) 
{ 
    echo $el.' '; if ($index % $cols ==0) echo '<br/>'; 
    $index++; 
} 

echo '<br/><br/>'; 

// special 
$rows = $cols ; 
$cols = floor(count($data)/$cols); 

for($row = 0 ; $row < $rows; $row++){ 

    for ($index = $row; $index < count($data); $index += $rows) 
    echo $data[$index].' '; 
    echo '<br/>'; 

}
