DomDocument->dump_file

(PHP 4 >= 4.1.0)

DomDocument->dump_file Dumps the internal XML tree back into a file

Description

string DomDocument->dump_file ( string $filename [, bool $compressionmode [, bool $format ]] )

Creates an XML document from the dom representation. This function usually is called after building a new dom document from scratch as in the example below. The format specifies whether the output should be neatly formatted, or not. The first parameter specifies the name of the filename and the second parameter, whether it should be compressed or not.

Example #1 Creating a simple HTML document header

<?php
$doc 
domxml_new_doc("1.0");
$root $doc->create_element("HTML");
$root $doc->append_child($root);
$head $doc->create_element("HEAD");
$head $root->append_child($head);
$title $doc->create_element("TITLE");
$title $head->append_child($title);
$text $doc->create_text_node("This is the title");
$text $title->append_child($text);
$doc->dump_file("/tmp/test.xml"falsetrue);
?>

See also domdocument_dump_mem(), and domdocument_html_dump_mem().

<?php
header
('Content-Type: text/xml');

$doc = domxml_new_doc("1.0");
$root = $doc->add_root("html");

$head = $root->new_child("head", "");
$head->new_child("title", "phpdom test");

echo
$doc->dump_mem();
$doc->dump_file("phpdom.xml", false, true);
?>

Also, It works

The string you pass as a filename should be an absolute path.

For Example:

$doc->dump_file(realpath("test.xml"),false,true);

Sometimes it maybe strange in the structure of the XML document when using false, true as the two boolean parameters. Using false, false can solve the problem.
