PHP simplexmlelement operation XML Namespace implementation Code _php tutorial

See this problem, the first reaction is namespace relationship, but I never used simplexml operation namespace, so I opened the manual to check the information, the problem is not resolved, and ultimately through Google to solve the problem.

The friend who raised the question posted the data source from: http://code.google.com/intl/zh-CN/apis/contacts/docs/3.0/developers_guide_protocol.html# Retrieving_without_query, the data structure is roughly as follows:
Copy CodeThe code is as follows:

This structure is in the above address, this is my formatted XML data, now to get similar to the " 456 The value in the.

The final code is as follows:
Copy CodeThe code is as follows:
$x = new SimpleXMLElement ($STR);
foreach ($x->entry as $t) {
Echo $t->id. "
";
Echo $t->updated. "
";
$namespaces = $t->getnamespaces (true);
$GD = $t->children ($namespaces [' GD ']);
Echo $GD->phonenumber;
}

Of course, if not written as above, it can be written like this:
Copy CodeThe code is as follows:
$x = new SimpleXMLElement ($STR);
foreach ($x->entry as $t) {
Echo $t->id. "
";
Echo $t->updated. "
";
$namespaces = $t->getnamespaces (true);
Notice the difference between this and the above paragraph
$GD = $t->children (' http://schemas.google.com/g/2005 ');
Echo $GD->phonenumber;
}

Just like the second way of writing is hard-coded, this is not very good, in case of changes in any day, you have to change the N-Multiple code.
Problems follow, such as the following paragraph:
Copy CodeThe code is as follows:

This non-standard XML, does not define a namespace, what to do? In this case, in fact, SimpleXMLElement has been directly resolved, but will be reported warnging, because he believes that the event namespace does not exist.
The workaround is to:
Copy CodeThe code is as follows:
$xml = @new simplexmlelement ($STR),//At the front Plus @ to suppress the error.
echo "
