How to create XML files
If you need to create XML files in PHP, you can do it without having to create the tags yourself with strings. This code shows you how to use the new_child functions to create an XML file.
<?
$doc = new_xmldoc('1.0');
$root = $doc->add_root('members');
$member = $root->new_child('member','');
$member->new_child('lastName','John');
$member->new_child('firstName','Adams');
$member->new_child('contribution','3400');
$member = $root->new_child('member','');
$member->new_child('lastName','Debra');
$member->new_child('firstName','Hones');
$member->new_child('contribution','2400');
$member = $root->new_child('member','');
$member->new_child('lastName','Jake');
$member->new_child('firstName','Tudor');
$member->new_child('contribution','1200');
$fp = @fopen('members.xml','w');
if(!$fp) {
die('Error cannot create XML file');
}
fwrite($fp,$doc->dumpmem());
fclose($fp);
?>
would create the following XML file.
<members>
<member>
<lastName>John</lastName>
<firstName>Adams</firstName>
<contribution>3400</contribution>
</member>
<member>
<lastName>Debra</lastName>
<firstName>Hones</firstName>
<contribution>2400</contribution>
</member>
<member>
<lastName>Jake</lastName>
<firstName>Tudor</firstName>
<contribution>1200</contribution>
</member>
</members>

Thank you
I am a fairly new coder, at least when it come to XML and this php code. I had a couple of questions. I am trying to make my php script duplicate and XML example I was given. I followed your advice above but there where a couple of differences between the two. I was hoping you might help me out on how to fix them.
1) in the XML sheet that I am trying to duplicate each child object is on a new line and indented. Using your method above everything appears on one line. Does this matter? Is there a fix? Even if it doesn't matter it would be ideal to have each child object on a new line.
For example:
<root>
<child1>value1</child1>
<child2>value2<child2>
<childchild1>subvalue1</childchild1>
</root>
As Opposed to:
<root><child1>value1</child1><child2>value2<child2><childchild1>subvalue1</childchild1></root>
2)fields that are blank in my example show up as:
<notblank1>value1</notblank1>
<blank />
<notblank2>value2</notblank2>
After implementing your method they show up as:
<notblank1>value1</notblank1>
<blank></blank>
<notblank2>value2</notblank2>
I know I am asking a lot but I could really use the help. Thanks for any suggestions.
