這是我的php代碼:
<div class="summary"><a href="#slide-$key"><h3>$ite??m->title</h3></a>
HTML;}?>
php 渲染頁(yè)面后， 返回 .我想要 $key 獲取其中的數(shù)量，那么如何獲得?
這是因?yàn)?simpleXML 結(jié)構(gòu)不是普通的數(shù)組，而是沒(méi)有數(shù)組索引的迭代器.
除了使用變量手動(dòng)跟蹤之外，我不知道還有其他解決方案:
$index = 0;$xml = simplexml_load_file('post.xml');foreach($xml->item 作為 $item ){....$索引++；}<?xml version="1.0" encoding="utf-8"?>
<items>
<item>
<title>This is title1</title>
<desc>This is desc1</desc>
<image></image>
<tudou></tudou>
</item>
<item>
<title>This is title2</title>
<desc>This is desc2</desc>
<tudou>55362137</tudou>
</item>
<item>
<title>This is title3</title>
<desc>This is desc4</desc>
</item>
</items>
here's my php code:
<div class="nav">
<ul>
<?php
$xml = simplexml_load_file('post.xml');
//print_r($xml);
foreach($xml->item as $key=>$item )
{
echo <<<HTML
<li>
<div class="published">
<span class="day">13</span>
Sep 2010
</div>
<div class="summary">
<a href="#slide-$key">
<h3>$item->title</h3>
</a>
</div>
</li>
HTML;
}
?>
</ul>
</div>
after php render the page,the <a href="#slide-$key"> return <a href=#slide-item>.
I want $key get the number of which ,
so how to get ?
This is because simpleXML structures are not normal arrays but iterators who do not have an array index.
I don't know of any other solution than keeping track manually using a variable:
$index = 0;
$xml = simplexml_load_file('post.xml');
foreach($xml->item as $item )
{
....
$index++;
}
這篇關(guān)于在 simpleXMLElement 的 foreach 循環(huán)中獲取子索引的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
