那些知道PHP和XML的人吗?那么请看看!
这是我的PHP代码:
<? $xml = simplexml_load_file("movies.xml");
foreach ($xml->movie as $movie){ ?>
<h2><? echo $movie->title ?></h2>
<p>Year: <? echo $movie->year ?></p>
<p>Categori: <? echo $movie->regions->region->categories->categorie ?></p>
<p>Country: <? echo $movie->countries->country ?></p>
<? } ?>
这是mys XML文件:
<?xml version="1.0" encoding="UTF-8"?>
<movies>
<movie>
<title>A movie name</title>
<year>2010</year>
<regions>
<region>
<categories>
<categorie id="3">Animation</categorie>
<categorie id="5">Comedy</categorie>
<categorie id="9">Family</categorie>
</categories>
<countries>
<country id="123">USA</country>
</countries>
</region>
</regions>
</movie>
<movie>
<title>Little Fockers</title>
<year>2010</year>
<regions>
<region>
<categories>
<categorie id="5">Comedy</categorie>
</categories>
<countries>
<country id="123">USA</country>
</countries>
</region>
</regions>
</movie>
</movies>
上述代码的结果是:
<h2>A movie name</h2>
<p>Year: 2010</p>
<p>Category: Animation</p>
<p>Country: USA</p>
<h2>Little Fockers</h2>
<p>Year: 2010</p>
<p>Category: Comedy</p>
<p>Country: USA</p>
我希望它像这样(见第一部电影的类别):
<h2>A movie name</h2>
<p>Year: 2010</p>
<p>Category: Animation, Comedy, Family</p>
<p>Country: USA</p>
<h2>Little Fockers</h2>
<p>Year: 2010</p>
<p>Category: Comedy</p>
<p>Country: USA</p>
注意:我也想知道如何在单词之间加上逗号,但在最后一个单词上没有逗号......

试试这个。
<?php
$xml = simplexml_load_file("movies.xml");
foreach ($xml->movie as $movie) {
echo '<h2>' . $movie->title . '</h2>';
echo '<p>' . $movie->year . '</p>';
$categories = $movie->regions->region->categories->categorie;
while ($categorie = current($categories)) {
echo $categorie;
echo next($categories) ? ', ' : null;
}
echo '<p>' . $movie->countries->country . '</p>';
}
?>

这就是你如何将foreach与simplexmlElement一起使用:
$xml = simplexml_load_file("movies.xml");
foreach ($xml->children() as $children) {
echo $children->name;
}
答案 2 :(得分:1)
您也需要遍历categorie
元素,就像迭代movies
一样。
echo '<p>';
foreach($movie->regions->region->categories->categorie as $categorie){
echo $categorie . ', ';
}
echo '</p>';
您可能也希望修剪尾随,
。
我的评论中提到的方法:
$categories = $movie->regions->region->categories->categorie;
while($category = current($categories)){
echo $category . next($categories) ? ', ' : '';
}
答案 3 :(得分:1)
<?php
$cat_out='';
foreach($movie->regions->region->categories->categorie as $cat){
$cat_out.= $cat.',';
}
echo rtrim($cat_out,',');
?>
答案 4 :(得分:0)
<? foreach($movie->regions->region->categories->categorie as $category) { ?>
<p>Categori: <?= $category ?></p>
<? } ?>
答案 5 :(得分:0)
function categoryList(SimpleXmlElement $categories){
$cats = array();
foreach($categories as $category){
$cats[] = (string) $category;
}
return implode(', ', $cats);
}
然后你可以从你的循环中调用它,如:
<? echo categoryList($movie->regions->region->categories); ?>
使用数组和implode
消除了对计数和检测最后一个类别的逻辑的需要。
在函数中隔离它使得它更容易维护,并且比嵌套循环更容易混淆(尽管可以肯定的是嵌套循环 令人困惑)。

试试这个
$xml = ... // Xml file data
$Json = Xml_to_Json($xml);
$array = json_decode($Json,true);
echo '<pre>'; print_r($array);
foreach ($array as $key => $value) {
foreach ($value as $key1 => $value1) {
echo '<h2>'.$value1['title'].'</h2>
<p>Year: '.$value1['year'].'</p>
<p>Category: ';
foreach ($value1['regions']['region']['categories']['categorie'] as $categoriekey => $categorie) {
echo $categorie.' ';
}
echo 'Animation</p>
<p>Country: '.$value1['regions']['region']['countries']['country'].'</p>';
}
}
function Xml_to_Json($array){
$xml = simplexml_load_string($array, "SimpleXMLElement", LIBXML_NOCDATA);
$json = json_encode($xml);
return $json;
}
