PHP避免在循环到数组的数组时使用double foreach [英] PHP avoid double foreach when looping into an array of an array

问题描述

我有这种数组:

Array ( [data] => Array ( [0] => Array ( [name] => Lskdjlkdsfj [start_time] => 2013-06-12 [timezone] => Europe/Rome [location] => Rome, Lazio [id] => 592087844156650 [rsvp_status] => attending ) ) [paging] => Array ( [previous] => https://graph.facebook.com/100004042705860/events?limit=25&since=1370995200&__paging_token=592087844156650&__previous=1 [next] => https://graph.facebook.com/100004042705860/events?limit=25&until=1370995200&__paging_token=592087844156650 ) ) 

要获取我正在执行的数据:

To get the data I am doing so:

    foreach ($fb_events as $data) {
    foreach ($data as $fb_event_data) {
        echo $fb_event_data['name'];
        echo $fb_event_data['start_time'];
    }
}

这是使用双foreach的最佳方法吗?有没有更好的方法可以循环到数组的数组中? 这个正在工作.我只是想知道我是否正在按照正确"的方式进行操作！

Is this the best way to do it, using a double foreach? Is there a better way to loop into an array of an array? This one is working. I am just wondering if I am doing it the "right" way!

推荐答案

如果顶级数组只有一个元素，则可以简化为

If the top level array only has a single element then this can be simplified as

foreach ($fb_events["data"]  as $fb_event_data) {
    echo $fb_event_data['name'];
    echo $fb_event_data['start_time'];
}
