它应该为他们所有人显示测试"！但它说阵列"
Its supposed to display "Test" for them all! but it says "Array"
答
访问 xpath 返回的 array 的元素...
Access the elements of the array returned from xpath...
PHP >= 5.4:
$title = $db->xpath($tq)[0];
PHP <5.4:
更新 PHP :-)
或
list($title,) = $db->xpath($tq);
或
$title = $db->xpath($tq);
$title = $title[0];
