### Get document namespaces

    <?php

    $xml = <<<XML
    <?xml version="1.0" standalone="yes"?>
    <people xmlns:p="http://example.org/ns">
        <p:person id="1">John Doe</p:person>
        <p:person id="2">Susie Q. Public</p:person>
    </people>
    XML;

    $sxe = new SimpleXMLElement($xml);

    $namespaces = $sxe->getDocNamespaces();
    var_dump($namespaces);

    ?>

&example.outputs;

    array(1) {
       ["p"]=>
       string(21) "http://example.org/ns"
    }

### Working with multiple namespaces

    <?php

    $xml = <<<XML
    <?xml version="1.0" standalone="yes"?>
    <people xmlns:p="http://example.org/ns" xmlns:t="http://example.org/test">
        <p:person t:id="1">John Doe</p:person>
        <p:person t:id="2" a:addr="123 Street" xmlns:a="http://example.org/addr">
            Susie Q. Public
        </p:person>
    </people>
    XML;

    $sxe = new SimpleXMLElement($xml);

    $namespaces = $sxe->getDocNamespaces(TRUE);
    var_dump($namespaces);

    ?>

&example.outputs;

    array(3) {
      ["p"]=>
      string(21) "http://example.org/ns"
      ["t"]=>
      string(23) "http://example.org/test"
      ["a"]=>
      string(23) "http://example.org/addr"
    }
