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 ?
676
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 )
{
....
$index++;
}
You could use SimpleXMLElement::xpath to return an array of the <item> elements, then access the array's keys as you want.
foreach ($xml->xpath('/items/item') as $key => $item)
