PHP - 如何显示父数组的所有孩子

Question

嗨，我可以解析数组，但我无法解析所有子项（子项），它只显示子项的第一项。

$xml_data = 
'<response> 
<item> 
    <name>Life Cover1</name> 
    <feature>Indexation1</feature> 
    <benefits> 
    <bitem>foo1</bitem> 
    <bitem>foo2</bitem> 
    </benefits> 
</item> 
<item> 
    <name>Life Cover2</name> 
    <feature>Indexation2</feature> 
    <benefits> 
    <bitem>fd1</bitem> 
    <bitem>foo3</bitem> 
    <bitem>foo4</bitem> 
    </benefits> 
</item> 
<item> 
    <name>Life Cover3</name> 
    <feature>Indexation3</feature> 
    <benefits> 
    <bitem>foo5</bitem> 
    <bitem>foo6</bitem> 
    </benefits> 
</item> 
</response> 
'; 

//Display Data output format View 
$xml = new SimpleXMLElement($xml_data); 

$items = $xml->xpath('//item'); 
$itemNames = $xml->xpath('//name'); 
$features = $xml->xpath('//feature'); 
$benefits = $xml->xpath('//benefits'); 

$DataSize = sizeof($items); 

echo '<table border="1" cellpadding="0" cellspacing="0"><tbody>'; 

foreach($items as $item){ 

    echo '<tr>'; 
    echo '<td>' . $item->name . '</td>'; 
    echo '<td>' . $item->feature . '</td>'; 
    echo '<td>' . $item->benefits->children() . '</td>'; 
    echo '</tr>'; 
} 
echo '</tbody></table>'; 

$ item-> benefits-> children（）;只显示第一个bitem，如何在这种解析输出中显示所有的bitem？

你可以试试这个：

$xml_data = 
'<response> 
<item> 
    <name>Life Cover1</name> 
    <feature>Indexation1</feature> 
    <benefits> 
    <bitem>foo1</bitem> 
    <bitem>foo2</bitem> 
    </benefits> 
</item> 
<item> 
    <name>Life Cover2</name> 
    <feature>Indexation2</feature> 
    <benefits> 
    <bitem>fd1</bitem> 
    <bitem>foo3</bitem> 
    <bitem>foo4</bitem> 
    </benefits> 
</item> 
<item> 
    <name>Life Cover3</name> 
    <feature>Indexation3</feature> 
    <benefits> 
    <bitem>foo5</bitem> 
    <bitem>foo6</bitem> 
    </benefits> 
</item> 
</response> 
'; 

//Display Data output format View 
$xml = new SimpleXMLElement($xml_data); 

$items = $xml->xpath('//item'); 
$itemNames = $xml->xpath('//name'); 
$features = $xml->xpath('//feature'); 
$benefits = $xml->xpath('//benefits'); 

$DataSize = sizeof($items); 

echo '<table border="1" cellpadding="0" cellspacing="0"><tbody>'; 

foreach($items as $item){ 

    echo '<tr>'; 
    echo '<td>' . $item->name . '</td>'; 
    echo '<td>' . $item->feature . '</td>'; 
    echo '<td>'; 
    $child_item = ''; 
    foreach($item->benefits->children() as $child) 
    { 
    $child_item .= $child.' ,'; 
    } 
    echo rtrim($child_item,' ,'); 
    echo '</td>'; 
    echo '</tr>'; 
} 
echo '</tbody></table>'; 

这将显示所有逗号分隔字符串中的子项。希望这会帮助你。
