php - 循环排序 foreach

Question

<?php
    $array = array(array("aaa1", "aaa2", "aaa3", "aaa4"),
                   array("bbb1", "bbb2", "bbb3", "bbb4"),
                   array("ccc1", "ccc2", "ccc3", "ccc4"), 
                   array("ddd1", "ddd2", "ddd3", "ddd4"));
    ?>
    <table border="2">
    <?php
    foreach($array as $arr): ?>
        <tr>
   <?php     foreach($arr as $a):
            echo "<td>" . $a . "</td>";
        endforeach; ?>
        </tr>
  <?php  endforeach;
    ?>
    </table>

这告诉我：

aaa1 aaa2 aaa3 aaa4
bbb1 bbb2 bbb3 bbb4
ccc1 ccc2 ccc3 ccc4
ddd1 ddd2 ddd3 ddd4

我想收到：

aaa1 bbb1 ccc1 ddd1
aaa2 bbb2 ccc2 ddd2
aaa3 bbb3 ccc3 ddd3
aaa4 bbb4 ccc4 ddd4

但我必须使用 FOREACH，而不是 FOR。如果这更容易，我可以使用 DIV，但是如何使用？

我怎样才能做到？

Answer 1

foreach(array_keys($array[0]) as $key) {
    echo "<tr>";
    foreach($array as $arr) {
        echo "<td>".$arr[$key]."</td>";
    }
    echo "</tr>";
}

虽然，你会更好for...

如果使用 DIV 是一个选项：

<?php
    $array = array(
        array("aaa1", "aaa2", "aaa3", "aaa4"),
        array("bbb1", "bbb2", "bbb3", "bbb4"),
        array("ccc1", "ccc2", "ccc3", "ccc4"), 
        array("ddd1", "ddd2", "ddd3", "ddd4")
    );
    foreach($array as $abcd) {
        ?><div style="float: left;"><?php
        foreach($abcd as $oneTwoThree) {
            ?><div><?php
            echo $oneTwoThree;
            ?></div><?php
        }
        ?></div><?php
    }
?>
<div style="clear: both;"></div>
