issue while reading xml file

Question

I have to read an XML file that resides on Fitnesse Page.

Let's take an example.

<?php
$url = http://localhost:9090/TestSuite.Fitnesse?Suite&Format=XML;
$xml=file_get_contents($url);
?>

My XML is in form of:

<xml version="some version">
<Results>
<name>Karan</name>
</Results>
...etc...

When I output the $xml on page, some strange numbers appears to come before each and every tag and output seems to be like

37 9 Karan 9f .........and so on....

When I checked the source of that webpage, the page containes the below code:

37 9
<?XML  Version="some version">
32
<Results>
32
<name>
45
Karan 
0f
</name>
and so on....

(I didn't use the exact value, I can provide if needed).

Can anybody help me on this as I was not expecting these strange characters in output string.

You need to have allow_fopen_url set in your server (php.ini) for this to work.

If you don´t, then you can use this function as a replacement:

<?php
function curl_get_file_contents($URL)
    {
        $c = curl_init();
        curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($c, CURLOPT_URL, $URL);
        $contents = curl_exec($c);
        curl_close($c);

        if ($contents) return $contents;
            else return FALSE;
    }
?>

this will require curl extension enabled in your php.ini
