我希望能够定义列数，但是，这并没有定义列。当您看到输出时，您会注意到它更改了行数而不是列数。

我已经尽可能详细地记录了，感谢您的所有帮助！第一次发帖，如有错误请多多包涵：）

public function SplitIntoColumns(array $arrayTranspose=array(), $no_of_cols=3,$min=0) {
    $result = '<div class="column">'."\n";
    // The 2D array
    $colArr = array();
    // The tmpArray
    $tmpArray = array();
    if (count($arrayTranspose) <= $min) {
        $result .= implode("\n", $arrayTranspose);
    }
    else {
        // Set size of the array    
        $cnt = intval(floor(count($arrayTranspose)));
        $row = 0;
        $col = 0;
        // Create Multidimensional array from Single dimensional array
        foreach($arrayTranspose as $key => $val){
            $colArr[$col][$row] = $arrayTranspose[$key];
            // Store the data from the array
            $result .= $colArr[$col][$row]." ";
            $col++;
            // If columns are equal to the set value then start
            // From the beginning on a new row
            if($col == $no_of_cols) {
                $col = 0;
                $row++;
                // create columns
                $result .= '</div><div class="column">'."\n";   
            }
        }
    }
    // This says numberOfRows, but it is actually the number of columns
    $numberOfRows = intval((floor($cnt) / $no_of_cols));
    // A loop to transpose into columns
    for($i = 0; $i <= $no_of_cols; $i++) {
        for($j = 0; $j <= $numberOfRows; $j++){
            $tmpArray[$j][$i] = $colArr[$i][$j];
            $result2 .= $tmpArray[$j][$i].' ';  
        }
        $result2 .= '</div><div class="column">'."\n";
    }
    // return stuff
    $result2 .= "</div> <!-- /.column -->\n";
    return $result2;
}
}
$Util = new SplitColumns();
$content = array('Lorem ipsum','elit sed do','labore et dolore', 'dolor sit amet', 'eiusmod tempor', 'magna aliqua',  'consectetur adipisicing', 'incididunt ut');
// This is where you can define the number of columns you want
// However, this does not define columns.  You will notice when
// You see the output that it changes the number of rows
echo $Util->SplitIntoColumns($content, 4);

输出：

Lorem ipsum eiusmod tempor
elit sed do magna aliqua
labore et dolore consectetur adipisicing
dolor sit amet incididunt ut

所需的输出应该是：

Lorem ipsum labore et dolore eiusmod tempor consectetur adipisicing
elit sed do dolor sit amet magna aliqua incididunt ut

你把事情复杂化了！结合array_chunk()一些简单的数学来正确格式化数据：

function splitIntoColumns($array, $columns=3)
{
    $numberOfRows = ceil(count($array) / $columns);
    return array_chunk($array, $numberOfRows);
}

这为您留下了一个列数组 - $returnValue[0] 是第 0 列中的元素数组，依此类推，直到列限制。示例输出（4 列）：

array(4) {
  [0]=>
  array(2) {
    [0]=>
    string(11) "Lorem ipsum"
    [1]=>
    string(11) "elit sed do"
  }
  [1]=>
  array(2) {
    [0]=>
    string(16) "labore et dolore"
    [1]=>
    string(14) "dolor sit amet"
  }
  [2]=>
  array(2) {
    [0]=>
    string(14) "eiusmod tempor"
    [1]=>
    string(12) "magna aliqua"
  }
  [3]=>
  array(2) {
    [0]=>
    string(23) "consectetur adipisicing"
    [1]=>
    string(13) "incididunt ut"
  }
}

从那里添加 HTML 应该相当简单，并且可以通过多种方式完成，例如：

$result = splitIntoColumns($inputArray, 3);

foreach($result as $column => $columnMembers)
{
    echo '<div class="column">';
    foreach($columnMembers as $key => $val)
    {
        echo $val; 
        //or whatever else you want to do in here
    }
    echo '</div> <!-- /column -->';
}

编辑： 带有 html 输出的示例

您可以通过更简单的方式获得预期的输出：

$content = array('Lorem ipsum','elit sed do','labore et dolore', 'dolor sit amet', 'eiusmod tempor', 'magna aliqua',  'consectetur adipisicing', 'incididunt ut');    
for($i = 0; $i<count($content); $i++){
    if($i % 2 == 0){
        $col1 .= $content[$i] . ' ';
    }
    else{
        $col2 .= $content[$i] . ' ';
    }
}    
echo $col1 . "\n" . $col2;

输出：

Lorem ipsum labore et dolore eiusmod tempor consectetur adipisicing
elit sed do dolor sit amet magna aliqua incididunt ut
