在PHP中获取对象的值失败

Question

我做print_r（$ img）;结果就是这个

SimpleXMLElement Object
(
    [0] => http://www.thestar.com.my/~/media/Images/TSOL/Photos-Gallery/features/2014/07/02/JamyYangMingjie020714.ashx?crop=1&w=460&h=345&

)

我想只获取链接列表。所以我做$ img [0]它不起作用，为什么？

Answer 1

您使用简单的foreach循环：

foreach($img as $i) {
    echo "<img src='". $i. "' />";
}
