如何在现有的单文件脚本中添加 xml 文件数组？

发布于 2024-11-18 02:17:17 字数 391 浏览 1 评论 0原文

以下代码获取文件的 fan_count 并显示它。我想要做的是创建一个可以容纳许多网址并回显每个网址的数组。

我该如何修改代码？谢谢

<?php

$dom = new DOMDocument;
$dom->loadHTMLFile ('domain.com/xmlfile.xml');

$xPath = new DOMXPath($dom);

$posts = $xPath->query('//page');

foreach($posts as $post) {

$fans = $post->getElementsByTagName( "fan_count" )->item(0)->nodeValue;
echo $fans;

}

?>

The following code gets the fan_count of the file and shows it. What I want to do is to create an array that can hold many urls and echo each one the fan_count.

How can I modify the code ? Thank you

<?php

$dom = new DOMDocument;
$dom->loadHTMLFile ('domain.com/xmlfile.xml');

$xPath = new DOMXPath($dom);

$posts = $xPath->query('//page');

foreach($posts as $post) {

$fans = $post->getElementsByTagName( "fan_count" )->item(0)->nodeValue;
echo $fans;

}

?>

$sum = $sum.$contents

$sum = $sum.$contents

is this ok?

尝试使用：

$feeds = array(
'https://api.facebook.com/method/fql.query?query=SELECT%20fan_count%20FROM%20page%20WHERE%20page_id=1234567',
'https://api.facebook.com/method/fql.query?query=SELECT%20fan_count%20FROM%20page%20WHERE%20page_id=7564321'
);

foreach ($feeds as $feed) {


$xml = simplexml_load_file($feed);

    $fans_numbers = $xml->xpath("//fan_count");
    foreach ($fans_numbers as $elem){
       print_r($elem);
    }

}

Try with:

$feeds = array(
'https://api.facebook.com/method/fql.query?query=SELECT%20fan_count%20FROM%20page%20WHERE%20page_id=1234567',
'https://api.facebook.com/method/fql.query?query=SELECT%20fan_count%20FROM%20page%20WHERE%20page_id=7564321'
);

foreach ($feeds as $feed) {


$xml = simplexml_load_file($feed);

    $fans_numbers = $xml->xpath("//fan_count");
    foreach ($fans_numbers as $elem){
       print_r($elem);
    }

}
