假设我有一个数组

$aSomeArray = array("1","2","3","4","5","6","7","8","9","10","11","12");

现在像这样在一个表格行中显示一个数组值很容易

echo "<table>";

foreach ($aSomeArray as $iSomeArrayKey => $iSomeArrayValue)
{   
     echo "<tr>";
     echo "<td>".$iSomeArrayValue."</td>";
     echo "</tr>";
}

echo "</table>";

但我想像这样以表格格式显示值

1    2    3    4
5    6    7    8
9    10   11   12

我怎样才能做到这一点？

编辑，这有效：

$aSomeArray = array("1","2","3","4","5","6","7","8","9","10","11","12");
$i = 0;
echo "<table>\r\n";
foreach ($aSomeArray as $aSomeArrayKey => $aSomeArrayValue)
{   
    if (($i % 4) == 0) echo "\t<tr>\r\n";
    echo "\t\t<td>" . $aSomeArrayValue . "</td>\r\n";
    if (($i % 4) == 3) echo "\t</tr>\r\n";
    $i++;
}
echo "</table>\r\n";

只是一个看起来更好恕我直言的想法。

<?php
$aSomeArray = array("1","2","3","4","5","6","7","8","9","10","11","12");

function createMatrix($width, $array)
{
 $newArray = array();
 $temp = array();
 $count = 1;

 foreach($array as $key => $value)
 {
  $temp[] = $value;

  if(($count++ % $width) == 0)
  {
   $newArray[] = $temp;
   $temp = array();
  }
 }
 if( count($temp) > 0)
 {
  $newArray[] = $temp;
 }
 return $newArray;
}

将创建一个变量矩阵数组$width 然后您可以使用该数据作为一个双 for-each 像这样：

$matrix = createMatrix(2, $aSomeArray );

foreach($matrix as $row)
{
 echo "<tr>\n";
 foreach($row as $td)
 {
  echo "\t<td>{$td}</td>\n";
 }
 echo "</tr>\n";
}

产生： 

<tr>
    <td>1</td>
    <td>2</td>
</tr>
<tr>
    <td>3</td>
    <td>4</td>
</tr>
<tr>
    <td>5</td>
    <td>6</td>
</tr>
<tr>
    <td>7</td>
    <td>8</td>
</tr>
<tr>
    <td>9</td>
    <td>10</td>
</tr>
<tr>
    <td>11</td>
    <td>12</td>
</tr>

只做一个运行计数。因此，在 foreach 集$i = 1和每四个结果之前，将计数重置为$i = 1然后结束该行并重新打开一个新行。

$aSomeArray = array("1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13");

$columns = 4; // The number of columns to shown

echo "<table>";

$i = 0;
$trOpen = false; // just a flag if <tr> has been closed (paired with </tr>) or not.
foreach ($aSomeArray as $item) {
    if ($i % $columns == 0) {
        echo "<tr>";
        $trOpen = true;
    }

    echo "<td>" . $item . "</td>";

    if (($i + 1) % $columns == 0) {
        echo "</tr>";
        $trOpen = false;
    }

    $i++;
}

if ($trOpen) {
    echo "</tr>"; // add '</tr>' if it is not yet added.
}

echo "</table>";

echo "<table>";
echo "<tr>";
foreach ($aSomeArray as $aSomeArrayKey => $aSomeArrayValue)
{   
 echo "<td>".$aSomeArrayValue."</td>";
 if($aSomeArrayValue % 4 == 0)
     echo "</tr><tr>";
}
echo "</tr>";
echo "</table>";

$i=1;
echo "<tr>";
foreach ($aSomeArray as $aSomeArrayKey => $aSomeArrayValue)
{   

     echo "<td>".$aSomeArrayValue."</td>";
     $i++;
     if($i%4==0){
         echo "<tr></tr>";
     }
}
echo "</tr>";

它也适用于不可被 4 个元素整除的元素。

试试这个代码

<?php
$i=0;
echo"<table>";
echo"<tr>";
foreach($aSomeArrayas as $val)
{
if($i %4 ==0)
  {
     echo"</tr><tr> <td> $val</td>";  
  }
  else
  {
    echo"<td> $val </td>";  
  }
  $i++;
}
echo"</tr>";
echo"</table>";
?>
