parse and display each node by way of foreach loop

i am trying to parse usernames on a twitter rss feed using simplexml in php. there are a total of 16 names so i will like to use the foreach loop to run parse each one and return them. my only problem is the foreach loop.

$url = file_get开发者_如何学JAVA_contents("http://search.twitter.com/search.atom?q=basketball");
$source = simplexml_load_string($url);

foreach ($source as $match){
    $output = $match->name(0)->nodeValue = substr($match->name(0)->nodeValue, 0, strpos($match->name(0)->nodeValue, ' '));
    echo $output;
}

Not sure what error you're having. But, judging from the feed itself, it seems that $match->name(0)->nodeValue is incorrect; as nodeValue is not a method of the SimpleXML library, but rather the Document Object Model library.

You can replace all occurrences of $match->name(0)->nodeValue with $match->author->name as ->name will output the node value for the tag <name>, which is a child of <author>.
