Php生成XML

我是新來的PHP。Php生成XML

我創建了一個可以用myPHPAdmin中的數據生成xml文件的php文件。感謝：D。希望可以有人幫幫我。

首先嚐試，代碼已經顯示在php中，當我打開檢查創建的XML。顯示'$node'，它反映了fwrite內部的確切字符串，當我嘗試刪除字符串quote（''），像這樣fwrite($dp,$node);。我得到錯誤。

而當我嘗試將代碼返回給fwrite（$ dp，'$ node'）;.沒有顯示。 XML頁面是空白的。

OMG，首先讓我歡迎你來到社區。請**注意**您不需要上傳您的所有代碼就問題。請僅張貼與該問題相關的代碼。否則，我們不會對回答它們感興趣。 – Starx 2012-02-26 08:45:12

phpMyAdmin不允許你直接下載XML格式的數據嗎？ – liquorvicar 2012-02-26 08:48:16

爲什麼使用DOM來創建一個新的XML文件並打開一個XML文件來編寫。首先檢查我的答案是否爲寫入方式 – Starx 2012-02-26 08:54:17

當您使用PHP創建XML文件時，您需要使用XML標頭。

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

但是，當您在最後使用saveXML()時不需要此功能。

這裏是一個例子，從php的手冊中挑選出來。

<?php 

$doc = new DOMDocument('1.0'); 
// we want a nice output 
$doc->formatOutput = true; 

$root = $doc->createElement('book'); 
$root = $doc->appendChild($root); 

$title = $doc->createElement('title'); 
$title = $root->appendChild($title); 

$text = $doc->createTextNode('This is the title'); 
$text = $title->appendChild($text); 

echo "Saving all the document:\n"; 
echo $doc->saveXML() . "\n"; 

echo "Saving only the title part:\n"; 
echo $doc->saveXML($title); 
?>
