Question

我有：

$l = array(
               array("A"=>0.1,"B"=>1,"C"=>1,"D"=>1),
               array("A"=>0.1,"B"=>1,"C"=>0,"D"=>2),
            );

$h = array('h1','h2');

1 - 我如何map(l,h)这个？

$result= $array(
               'h1'=> array("A"=>0.1,"B"=>1,"C"=>1,"D"=>1),
               'h1'=> array("A"=>0.1,"B"=>1,"C"=>0,"D"=>2),
            );

2-所以我可以显示（现在的html表格）

-------------------
   | A | B | C | D  
-------------------
h1 |
-------------------
h2 |
--------------------

我试图输出：

<table>
<tr><td>A</td><td>B</td><td>C</td><td>D</td></tr>
foreach($result as $key=>$value){
  <tr>

  <tr>
}
<table>

任何人都可以帮助我？

Answer 1

按照您的建议映射数组很简单：

$mapped = array_combine($h, $l);

然后：

// Print the top "headers" row
$columns = array_keys(reset($l));
echo '<table><tr><td>&nbsp;</td>';
foreach ($columns as $column) {
    echo '<td>'.$column.'</td>';
}
echo '</tr>';

// Print each data row
foreach ($mapped as $key => $row) {
    echo '<tr><td>'.$key.'</td>';
    foreach ($row as $cell) {
        echo '<td>'.$cell.'</td>';
    }
    echo '</tr>';
}

// Done!
echo '</table>';

Answer 2

$result = array_combine($h, $l);

这适用于bc数组元素有隐含的数字索引，因为您可以看到var_dump($h)或var_dump($l)

<table>
<?php
    echo "<tr>";
    echo "<td>&nbsp</td>";
    foreach(array_keys($l[0]) as $letter)
        echo "<td>$letter</td>"; //A,B,C,D
    echo "</tr>";
    foreach($result as $h_key=>$innerArr)
    {
        echo "<tr><td>$hkey</td>"; //h1,h2
        foreach($innerArr as $key=>$val)
           echo "<td>$val</td>";  //0.1, 1, etc.
        echo "</tr>";
    }
?>
</table>

映射数组并显示它？
