Question

我需要在表格中以特定的方式显示数组数据，所以我需要像这样格式化我的数组：

               Leafy Life - Aspley - All Green
Callistemon1 -     33     -        - 
Callistemon2 -            -        - 3.59
Acronychia   -            -  22.5  -

如果有人能指出我正确的方向，甚至调整我非常感激的代码。

$options = array(
array("plant" => "Callistemon Kings Park Special 300 mm","nursery" => "A Leafy Life","price" => "33"),
array("plant" => "Callistemon Kings Park Special 300 mm","nursery" => "Alpine Nurseries Alstonville","price" => "23"),
array("plant" => "Callistemon Kings Park Special 140 mm","nursery" => "All Green Nursery","price" => "3.59"),
array("plant" => "Acronychia imperforata 300 mm","nursery" => "Aspley Nursery","price" => "22.5"),
array("plant" => "Acronychia imperforata 300 mm","nursery" => "All Green Nursery","price" => "23"),
array("plant" => "Metrosideros collina Little Dugald  140 mm","nursery" => "Accent Plants","price" => "5.25"),
);

$newOptions = array();
foreach ($options as $option) {
 $plant = $option['plant'];
 $nursery = $option['nursery'];
 $price = $option['price'];

 $newOptions[$plant][$nursery] = $price;
}

print_r($newOptions);

echo "<table cellpadding='0' cellspacing='0' border='2'>";
echo "<thead>";
echo "<th></th>";
foreach($newOptions as $key => $row) 
{ 
    foreach($row as $k => $v) 
    {
        print_r($k);
        echo "<th>";
        echo $k;
        echo "</th>";
    }       
}
echo "</thead>";

echo "<tbody>";
$i=0;
foreach($newOptions as $keys => $rows) 
{ 
    echo "<tr>";
    echo "<td>";
    echo $keys;
    echo "</td>";

    foreach($rows as $v) 
    {

            echo "<td>";
            echo "&nbsp;". $i;
            echo "</td>";

        $i++;
        echo "<td>";
        echo $v;
        echo "</td>";

    }

    echo "</tr>";
}

echo "</tbody>";
echo "</table>";


?>

Answer 1

我们可以像这样更改数组的结构 -

$Headers = array();
$headers[1] = "Leafy Life";
$headers[2] = "Aspley";
$headers[3] = "All Green";

$firstCloumnEntries = array();
$firstCloumnEntries[1] = "Callistemon1";
$firstCloumnEntries[2] = "Callistemon2";
$firstCloumnEntries[3] = "Acronychia";

$values = array();
$values[1] = array(); // this will have all values for first row;
$values[1][1] = "33";

$values[2] = array(); // this will have all values for second row;
$values[2][3] = "3.59";

$values[1] = array(); // this will have all values for third row;
$values[3][2] = "22.5";

现在在显示时 - 首先添加所有列“header”数组中的所有内容。

然后对于每一行 - 使用“firstCloumnEntries”数组使用循环索引获取第一个值。编写内部循环以打印相应的行值。在打印该值之前，请使用isset()。

由于我们在第0列第0行没有任何值，故意删除索引“0”。标题数组或firstCloumnEntries数组中的索引将帮助我们理解其中元素的ID，例如1是“Leafy Life”的ID，2是“Aspley”等等...使用此我们可以添加更多标题新ID和更多具有更多ID的firstCloumnEntries。这有助于添加动态内容并简化循环。

这是我正在使用的实际数组。

这是我的表

<table cellpadding='0' cellspacing='0' border='2'>
<thead>
<th></th>
<?php
foreach($nurseries as $key => $row) 
{ 
    echo "<th>";
    echo $key;
    echo "</th>";
}       

?>
</thead>
<tbody>
<?php
foreach($nurseries as $keys => $rows) 
{ 
    foreach($rows as $k => $v) 
    {
        echo "<tr>";
        echo "<td>";
        echo $k;
        echo "</td>";

        foreach($v as $key => $s) 
        {
            echo "<td>";
            echo $key;
            echo "</td>";           
        }
    }

    echo "</tr>";
}
?>
</tbody>
