Trying to get property of non-object -> xml

I'm retrieving an xml:

$xml = file_get_contents($query);

echo $xml->Email;
echo $xml[0]->Email;

The xml (echo $xml) looks like this:

<GetUserInfo>
<Customer>TestUser</Customer>
<Email>[email protected]</Balance>
</GetUserInfo>

But both those approaches give the following error:

Notice: Trying to get property of non-object in test.php on line 86

Notice: Trying to get property of non-object in test.php on line 87

How can I get the value of Email and Customer?

Your $xml is a string. $xml-> accesses a property of an object. That is not compatible. A php string is not an object.

You may want to use var_dump() instead of echo() to see all the details of your variables.

A simple string to object convertor is simplexml_load_string()

$xml='
<GetUserInfo>
<Customer>TestUser</Customer>
<Email>[email protected]</Email>
</GetUserInfo>
';

var_dump($xml);
$Xml = simplexml_load_string($xml);
var_dump($Xml);
echo($Xml->Email);

file_get_contents() returns the file content, not an object. You can only use preg_match if you want to stick to string content (totally not advised):

preg_match('~<Email>([^<]+)</Email>~i', file_get_contents($__filePath__), $emails);

I recommend using DOMDocument and DOMXPath (code not tested):

$XMLDoc = new DOMDocument();
$XMLDoc->load($__filePath__);
$XPath = new DOMXPath($XMLDoc);
$emails = $XPath->query('//email');
foreach ($emails as $email)
    var_dump($email->nodeValue);

You might use another Xpath expression like //email[1] or /GetUserInfo/Email The foreach may also be replaced by $email = reset($emails); if you only want the first mail.
