Question

我正在尝试使用magpie拉出RSS项目的第一个缩略图图像，但如果项目中有多个图像，则会将它们全部返回到一个字符串中。

RSS代码：

喜鹊调试器返回两个图像：

["multimedia_media_thumbnail"]=>
  string(145) "http://media.jrn.com/images/300*377/K0008499127--75534.JPGhttp://media.jrn.com/images/300*213/mccormick_1436280885241_20971671_ver1.0_640_480.jpg"

如何获取multimedia_media_thumbnail的第一张图片网址？
