只需转到应用商店更新<html>
<body>
<?php
include_once('semsol/ARC2.php'); /* ARC2 static class inclusion */
$dbpconfig = array
(
"remote_store_endpoint" => "http://dbpedia.org/sparql",
);
$store = ARC2::getRemoteStore($dbpconfig);
if ($errs = $store->getErrors())
{
echo "<h1>getRemoteSotre error<h1>" ;
}
$query = '

}
';
$rows = $store->query($query, 'rows'); /* execute the query */
if ($errs = $store->getErrors())
{
echo "Query errors" ;
print_r($errs);
}
/* display the results in an HTML table */
echo "<table border='1'>" ;
foreach( $rows as $row )
{
/* loop for each returned row */
print "<tr><td>" .$row['l'] . "</td><td>" . $row['c']. "</td></tr>";
}
echo "</table>"
?>
</body>
</html>
然后重启，即可解决。
