Question

由于某种原因，当我使用fopen时，我收到以下错误：

无法打开流：HTTP包装器不支持/examplefolder/examplefile.php中的可写连接

当我使用它时：

<?php
$myFile = "http://url.com/" . $_COOKIE['user'] . "/current_pro_pic.xml"; 
$xmlw = new XMLWriter; 
$xmlw->setIndent(true); 
$xmlw->startDocument('1.0', 'UTF-8');  
$xmlw->startElement('user_current_pro_pic'); 
$xmlw->writeElement('full_url', "<![CDATA[sometexthere*]]>"); 
$xmlw->writeElement('time', date('l F jS Y ') . 'at' . date(' h:i A')); 
$xmlw->endElement(); 
$xmlw->endElement(); 
$xmlw->endElement(); 
$xmlw->endDocument(); 
?>

它吐出了这个：

Warning: XMLWriter::setIndent() [xmlwriter.setindent]: Invalid or unitialized XMLWriter object in *** on line 4

Warning: XMLWriter::startDocument() [xmlwriter.startdocument]: Invalid or unitialized XMLWriter object in *** on line 5

Warning: XMLWriter::endElement() [xmlwriter.endelement]: Invalid or unitialized XMLWriter object in *** on line 11

Warning: XMLWriter::endDocument() [xmlwriter.enddocument]: Invalid or unitialized XMLWriter object in *** on line 12

有谁知道为什么会这样？它不是fyi的文件权限。

Answer 1

标准从网页获取，始终是只读的。服务器得到一个问题，并将答案发送给您。如果你想给它写XML，你需要发布它，或者把它作为get的变量发送（后者是空间限制的）

Answer 2

您无法使用http网址引用文件来编写文件。即使文件在同一台服务器上，您也必须为文件提供文件系统路径。

Answer 3

您必须调用其中一个开放*方法，例如openMemory，openUri

$xmlw = new XMLWriter; 
$xmlw->openUri('path_to_save');
// ... or
$xmlw->openMemory();
// ... youe code
$xmlw->setIndent(true); 
// ...
