DomDocument::dump_file

(PHP 4 >= 4.1.0)

DomDocument::dump_file — Dumps the internal XML tree back into a file

说明

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", false, true);
?>

<?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.

the return value contains the number of bytes, wich are written by this command
