Question

我有以下内容：

<table border="1">
<?php
 $i = 0;
$tmp = 1;
foreach ($recip['Data']['Recipes'] as $key => $recipe) {
        $tmp = $i % 2;
        echo $tmp; 
        if($tmp == 0) {
            echo '<tr>';
        }
        echo '<td>
                  <a href="/recipe_search.php?id=' . $recipe['ID'] . '">';
        echo  $recipe['TITLE'];
        echo '</a> </td>';
        if($tmp == 0){
            echo '</tr>';
        }
        $i = $i + 1;    
 } 
 ?>
</table>

我想要的是，两个值在一行中。因此，如果$tmp为偶数，则应启动新行。不幸的是，代码不会这样做，每个值都代表一个新行。我该如何管理？

<table border="1">
<?php
 $i = 0;

foreach ($recip['Data']['Recipes'] as $key => $recipe) {
        if($i % 2 == 0) {
            echo '<tr>';
        }
        echo '<td><a href="/recipe_search.php?id=' . $recipe['ID'] . '">';
        echo  $recipe['TITLE'];
        echo '</a> </td>';
        if(($i+1) % 2 == 0){
            echo '</tr>';
        }
        $i++;    
 } 
 // if there is an odd number of entries, the last one will include only one recipie.
 // but we must still echo </tr>
 if(count($recip['Data']['Recipes']) % 2 != 0){
    echo '</tr>';
 }
 ?>
</table>

如果var = 0，则为新表行
