来自XML的PHP Echo foreach

我正在读取包含以下内容的xml文件：

<imageref>image1.jpg|image2.jpg|image3.jpg|image4.jpg</imageref>
<hotelname>villa test</hotelname>


foreach ($filtered as $hotel) {     
    $xmlhotels[] = array(        
        'image'=>(string)$hotel->imageref,
        'villaname'=>(string)$hotel->hotelname
    );
}

如何仅回显xml文件中的第一个图像（image1.jpg）。

使用并执行以下操作：

foreach ($filtered as $hotel) {     
    $xmlhotels[] = array(        
        'image'=>explode('|', $hotel->imageref),
        'villaname'=>(string)$hotel->hotelname
    );
}

foreach ($myhotels as $villa) {    
    echo $villa['villaname'];
    echo $villa['image'][0];
}

foreach ($filtered as $hotel) {     
    $xmlhotels[] = array(        
        'image'=>explode('|', $hotel->imageref),
        'villaname'=>(string)$hotel->hotelname
    );
}

foreach ($myhotels as $villa) {    
    echo $villa['villaname'];
    echo $villa['image'][0];
}
