Question

我想将PHP文件中的内容复制到XML中：

$channel = "15";
$start = "20180124021100 +0200";
$stop = "20180124031500 +0200";
$title = "news";
$desc = "show number 50";

我需要稍后循环并添加更多频道，所以我不想只编辑XML，

我想打开XML文件并将PHP内容添加到特定位置的页面中：

XML：

<?xml version="1.0" encoding="UTF-8"?>

<channel id="1">
<display-name lang="he">1</display-name>
</channel>

// I want the content to stick to the end

<programme start="$start" stop="$stop" channel="$number">
<title lang="he">$title</title>
<desc lang="he">$desc</desc>
</programme>

// And that the next loop will be the same, will paste the content to the end as well:

<programme start="$start" stop="$stop" channel="$number">
<title lang="he">$title</title>
<desc lang="he">$desc</desc>
</programme>

SimpleXML for PHP使用相当简单，无论是读取还是编写XML。在这个问题How to convert array to SimpleXML中，您可以找到许多关于在PHP中使用SimpleXML的建议。可以在此处找到文档：https://secure.php.net/manual/en/book.simplexml.php

不是使用字符串来构建XML，而是应该查看现有的一个类来完成所有繁重的工作 - 它们毕竟是为此目的而设计的。查看问题中的xml，它看起来不是有效的XML，因为内容没有根节点。以下内容应该有助于开始。

<?php

    $channel = "15";
    $start = "20180124021100 +0200";
    $stop = "20180124031500 +0200";
    $title = "news";
    $desc = "show number 50";




    /* file path to saved xml document */
    $xmlfile= __DIR__ . '/xmlfile.xml';

    /* whether to display XML in browser or simply save */
    $displayxml=true;


    /* create DOMDocument and set args */
    $dom=new DOMDocument('1.0','utf-8');
    $dom->standalone=true;
    $dom->formatOutput=true;
    $dom->recover=true;
    $dom->strictErrorChecking=true;

    /* a ROOT node for the document */
    $rootnode='programmes';

    /* if the file already exists, open it */
    if( realpath( $xmlfile ) ){

        $dom->load( $xmlfile );
        $root=$dom->getElementsByTagName( $rootnode )->item(0);

    } else {
        /* File does not exist, create root elements & content */
        $root=$dom->createElement( $rootnode );
        $dom->appendChild( $root );

        $ochan=$dom->createElement('channel');
        $ochan->setAttribute('id',1);
        $root->appendChild( $ochan );

        $odisp=$dom->createElement('display-name',1);
        $odisp->setAttribute('lang','he');
        $ochan->appendChild( $odisp );      
    }


    /* process variables for new record/programme */
    if( isset( $channel, $start, $stop, $title, $desc ) ){

        $oprog=$dom->createElement('programme');
        $root->appendChild( $oprog );

        $oprog->setAttribute('start',$start);
        $oprog->setAttribute('end',$stop);
        $oprog->setAttribute('channel',$channel);


        $otitle=$dom->createElement('title',$title);
        $oprog->appendChild($otitle);
        $otitle->setAttribute('lang','he');


        $odescr=$dom->createElement('desc',$desc);
        $oprog->appendChild($odescr);
        $odescr->setAttribute('lang','he');
    }
    /* save the file */
    $dom->save( $xmlfile );

    /* if you want to see the generated xml in the browser */
    if( $displayxml ){
        header('Content-Type: application/xml');
        echo $dom->saveXML();
    }
?>

如何用PHP将内容添加到xml？
