无法拆分从网页解析的字符串？

Question

在这里，我正在解析一个网页，并从该网页获取'name‘字段。以下是执行解析的代码：

foreach($dom->getElementsByTagName('table') as $table) {
    if($table->getAttribute('class')=='dataTable'){
        foreach($table->getElementsByTagName('tr') as $tr){
            if(isset($tr->getElementsByTagName('td')->item(0)->nodeValue)){
                $out[$i]['name'] = $tr->getElementsByTagName('td')->item(0)->nodeValue;
            }
        }
    }
}

在我正在解析的网页中，我有name的节点值，格式为‘Mark和Smith’。因此，当我得到结果时，我在集成开发环境中将“name”值设置为“Mark Smith”，在命令提示符中将“Mark┬áSmith”设置为“Mark Smith”。

现在我想以这样的方式拆分'name‘字符串，这样我就可以分别得到名字(’Mark‘)和姓氏(’smith‘)。

我试过了：

explode(" ", $out[$i]['name']) as well as
explode(" " , $out[$i]['name'])

但似乎没有一样东西对我有效。帮我把字符串拆分成名字和姓氏？

希望我的问题说清楚了。

@user1518659在这里试试这个，为了解决这个问题，只需在传递给DOMDocument之前将 替换为一个空格，我还添加了名字和姓氏的拆分:)希望它能有所帮助。

试着解决这个问题：

explode(chr(0xC2).chr(0xA0), $str)

UTF-8中存在两个字节的不间断空格: 0xC2和0xA0。

您在那里拥有的非中断空格字符实体已损坏。应该是 。请注意分号。

要回答您的问题，您可以简单地这样做：

var_dump(explode('&nbsp', $out[$i]['name']));

或者，如果实体是固定的：

var_dump(explode(' ', $out[$i]['name']));
