在json_decode之后,我有以下数组:::
$json = Array ( [name] => Array ( [0] => Peter [1] => David ) [dep] => Array ( [0] => accounts [1] => sales ) [date] => Array ( [0] => 10/27/2015 [1] => 09/25/2015 ) );
如何按键对值进行分组,以便在PHP foreach循环中获得以下内容? :::
<ul>
<li>Peter, accounts, 10/27/2015</li>
<li>David, sales, 09/25/2015</li>
</ul>
我尝试了一个类似的foreach循环(见下文)而没有达到预期的效果,我能够打印所有关键字&amp;价值,但我无法按键对值进行分组,例如。 [1] :::
foreach($json as $row){
foreach($row as $key=>$val){
echo $key . ': ' . $val . '<br>';
}
}
任何帮助都将受到赞赏:::

您可以使用以下代码对列表进行排序:
<?php
$json = [
"name" => ["Peter","David"],
"dep" => ["accounts", "sales"],
"date" => ["10/27/2015","09/25/2015"]
];
$final = [];
foreach($json as $section)
{
foreach($section as $key=>$info)
{
if(!isset($final[$key])) $final[$key] = "";
$final[$key] .= $info . ", ";
}
}
echo "<ul>";
foreach($final as $row)
{
echo "<li>" . substr($row, 0, strlen($row) - 2) . "</li>"; // -2 to remove the extra ", "
}
echo "</ul>";
?>
结果:
<ul>
<li>Peter, accounts, 10/27/2015</li>
<li>David, sales, 09/25/2015</li>
</ul>

也许尝试这样的事情:
$arrayCount = count($json['name']);
$output = '<ul>';
for($i = 0; $i < $arrayCount; $i++) {
$output .= '<li>';
$output .= $json['name'][$i] . ', ';
$output .= $json['dep'][$i] . ', ';
$output .= $json['date'][$i];
$output .= '</li>';
}
$output .= '</ul>';
echo $output;
您最好使用这样的数组格式:
$json =
Array(
Array(
'name' => 'Peter',
'dep' => 'accounts',
'date' => '10/27/2015'
),
Array(
'name' => 'David',
'dep' => 'accounts',
'date' => '09/25/2015'
)
);
这是因为您可以创建一个更容易理解的foreach循环:
$output = '<ul>';
foreach($json as $row) {
$output .= '<li>';
$output .= $row['name'] . ', ';
$output .= $row['dep'] . ', ';
$output .= $row['date'];
$output .= '</li>';
}
$output .= '</ul>';
echo $output;
