PHP SimpleXML: Function Save

PHP Version: (no version information might be only in CVS) I tried with PHP5 and it works.

Description

Creates an XML document from the dom representation. The number of bytes written is returned. This function is usually called after building a new dom document from scratch as in the example below.

Usage

intDOMDocument->save ( string filename)

The filename is the name of the file in which the xml file will be written.

Example of How to use save():

<?php

$xmlstr = <<<XML

<employee>

<employeename>test</employeename>

<employeeaddress>test123</employeeaddress>

<SSN>12343456</SSN>

<company>TOPXML</company>

</employee>

XML;

$dom = new domDocument;

$dom->loadXML($xmlstr);

$test = $dom->save("C:/topxml_demo/php/xml_files/save.xml");

echo "The number of bytes written :".$test;

?>

In the above example, I first created a new XML document from the domDocumentclass by using the new keyword, and then I pull XML string( $xmlstr) into the DOMDocument object using the loadXMLfunction of the object. Finally, I saved the DOMDocument into a file using save() function and echo out the number of bytes written.

Output:

You will find a file named save.xml in /php/xml_files directory.
