在 PHP 中包含 XML 编码

Question

我是 PHP 和 XML 的初学者。

当我编写一个新的 xml 文件时，有人可以告诉我如何包含 XML 编码。

以下是代码：

writexml.php

<?php 
 $ids =  array("1", "2", "3", "4", "5");
 $names = array("Jean Claude Van Damme", "Scott Adkins", "Dolph Ludgren", "Michael Jai White", "Michael Worth");

 $domdoc = new DOMDocument(); 
 $domdoc->formatOutput = true; 

 $el_actionstars = $domdoc->createElement( "actionstars" ); 
 $domdoc->appendChild( $el_actionstars  ); 

 $arr_size = count($ids);

 for ($i=0; $i < $arr_size; $i++) {
  $el_actionstar = $domdoc->createElement( "actionstar" ); 

  $el_id =  $domdoc->createElement( "id" ); 
  $el_id->appendChild( $domdoc->createTextNode($ids[$i] . "")); 
  $el_actionstar->appendChild($el_id);

  $el_name =  $domdoc->createElement( "name" ); 
  $el_name->appendChild( $domdoc->createTextNode($names[$i] . "")); 
  $el_actionstar->appendChild($el_name);


  $el_actionstars->appendChild($el_actionstar);
 }

 echo $domdoc->saveXML(); 
 $domdoc->save("actionstars.xml") 
?>

The xml output is <?xml version="1.0"?> and I want to add the encoding to make it look like <?xml version="1.0" encoding="ISO-8859-1"?> . 请帮助...

Answer 1

尝试在您的实例化中使用它：

/**
 * <?xml version="1.0" encoding="UTF-8" ?>
 */
$domdoc = new DOMDocument('1.0', 'UTF-8');

如此处所示： http://php.net/manual/en/domdocument.construct.php

Answer 2

见底部http://php.net/manual/en/domdocument.savexml.php

当您保存整个文档时： DOMDocument->saveXML() 在属性 DOMDocument->encoding 中定义的编码中生成字符串。

当您只保存一个节点时：DOMDocument->saveXML(DOMNode) 总是在 UTF-8 中生成字符串。

您可以在构造函数中设置它

DOMDocument::__construct ([ string $version [, string $encoding ]] )

例如，

$domdoc = new DOMDocument('1.0', 'iso-8859-1');

Answer 3

尝试使用new DomDocument('1.0', 'UTF-8');
