Simple PHP script to create XML file, not working; blank screen 1

I edited this little bit of code to test to see why writing to an XML file using DOM/XML in PHP is not working and I get no errors nor any sort of result (like an xml file). I checked and the directory is CHMOD 777 if that matters.

Any ideas would be appreciated.

Code: 
<?php
$xmlDocument = domxml_new_doc('1.0');
$documentElement = $xmlDocument->create_element('forest');
$xmlDocument->append_child($documentElement);
$tree = $xmlDocument->create_element('tree');
$name = $xmlDocument->create_element('name');
$name->append_child($xmlDocument->create_text_node('Oak'));
$tree->append_child($name);
$documentElement->append_child($tree);
$xmlDocument->dump_file('test2005.xml', FALSE, TRUE);
?>

Absolutely nothing. I added 2 echos one before the PHP code and one after.

Code: 
<?php
echo "Begin";
$xmlDocument = domxml_new_doc('1.0');
$documentElement = $xmlDocument->create_element('forest');
$xmlDocument->append_child($documentElement);
$tree = $xmlDocument->create_element('tree');
$name = $xmlDocument->create_element('name');
$name->append_child($xmlDocument->create_text_node('Oak'));
$tree->append_child($name);
$documentElement->append_child($tree);
$xmlDocument->dump_file('test2005.xml', FALSE, TRUE);

print_r ($xmlDocument);
echo "End";
?>

I get the "Begin" but nothing else. Would something not be setup properly on the server, perhaps, that I could ask my host about? Or is it just the code?

Thanks for your help.

What are the values in your php.ini for display_errors and error_reporting?

What happens if you edit the script thusly:

Code: 
<?php
echo "Begin";
$xmlDocument = domxml_new_doc('1.0');
echo "1";
$documentElement = $xmlDocument->create_element('forest');
echo "2";
$xmlDocument->append_child($documentElement);
echo "3";
$tree = $xmlDocument->create_element('tree');
echo "4";
$name = $xmlDocument->create_element('name');
echo "5";
$name->append_child($xmlDocument->create_text_node('Oak'));
echo "6";
$tree->append_child($name);
echo "7";
$documentElement->append_child($tree);
echo "8";
$xmlDocument->dump_file('test2005.xml', FALSE, TRUE);
echo "9";

print_r ($xmlDocument);
echo "End";
?>

That's one way to see where it dies. Good thinking. (Not sure why I didn't think of that...)

I get:
Begin12345.

The settings you asked about returned this:
display_errors =
error_reporting = 2047

I am definitely new at PHP, but can I change the settings using ini_set? If so, do I change them now and then change them back when the page is live?

Thanks again for your help.

Changes made to php.ini settings via ini_set() are only good for that run of the script. The function does not make permanent changes to your PHP configuration.

Try changing that display_errors value to 1 and see what you get.

WOOOHOOOO!!! Errors never looked so beautiful!

Code: 
Begin12
Warning: domnode::append_child() expects parameter 1 to be object, null given in E:\WEB\harieonline\admin\test2.php on line 13
345
Fatal error: Call to a member function append_child() on a non-object in E:\WEB\harieonline\admin\test2.php on line 19

That gives me something to go by. I'll see if I can do some reasearch using these errors and see what comes up.

Thanks for your help!
