[RESOLVED] SimpleXML

[farius]

Lately I have been trying to get into the XML trend and use it for my configuration files instead of using .txt not for any reason other than I like that XML is a little neater.

Naturally I started off at the PHP website looking at all the choices for XML manipulation. I (for the moment) chose SimpleXML to start with and have hit a roadblock.

How can I change a value in the file itself. Here is a code example of how I was thinking it would work:

$xml = new SimpleXMLElement("config.xml",NULL,TRUE);
print $s->node . "\n"; //Prints SOMETHING
$s->node = "NOTHING";
print $s->host . "\n"; //Prints NOTHING

Great on first appearance it looks great, it changed the value and we are all set but with a little investigating and double checking I found it did not.

What am I doing wrong?

Here's an example, hope it helps:

<?php
$xml_file = 'xml_test.xml';

/**
xml_test contains:
<?xml version="1.0"?> 
<record>
<max>100</max>
<date>Jan 2, 2009</date>
<user>
<name>John</name>
<score>82</score>
</user>
<user>
<name>Paul</name>
<score>91</score>
</user>
</record>
**/

$sxml = simplexml_load_file($xml_file);
$sxml->date = date('M j, Y');
foreach ($sxml->user as $each) {
    if ($each->name == 'John') {
        $each->score = '88';
    }
    if ($each->name == 'Paul') {
        $each->score = '92';
    }
}

file_put_contents($xml_file, $sxml->asXML());

echo htmlspecialchars(file_get_contents($xml_file));
?>

Ahhh ok so you change it in memory and then re-write the file....

Thank you very much, really appreciate it!
