uri for the output.
uriThe URI of the resource for the output.
面向对象风格: 成功时返回 TRUE， 或者在失败时返回 FALSE。
过程化风格: Returns a new xmlwriter 资源(resource) for later use with the
xmlwriter functions on success, FALSE on error.
Reproduced on Windows:
If you get an exception when you try to handle the created file (rename, move etc.) you should unset the XMLWriter instance.
In other case you'll get an exception because the XMLWriter process holds access to this file.
<?php
$xml = new \XMLWriter();
$xml->openUri(...)
...
$xml->flush();
unset($xml); //important!
I wanted to stream a XML file directly to the user and having him prompted to save it without displaying the content, but when using
<?php
$out =new XMLWriter();
$out->openURI('php://output');
?>
the user's browser was displaying the file contents instead of prompting the user with a filesave window.
To have the XML file stream saved directly to the user without being displayed by the browser, you shoud add:
<?php
header("Content-Type: text/html/force-download");
header("Content-Disposition: attachment; filename='file_name.xml'");
$out =new XMLWriter();
$out->openURI('php://output');
?>
This will prompt the user with a dialog box to save 'file_name.xml' on his disk, and will not display the content of the streamed XML.
Want to write xml-data directly to the user instead of memory or file?
This will do:
<?php
$out =new XMLWriter();
$out->openURI('php://output');
?>
