问题是它返回了一个 stdClass 而不是一个数组,你可以通过 using 来判断,var_dump($facebook)
将 stdClass 转换为数组 use get_object_vars()
。
这是您的解决方案:
<?php
$facebook = get_object_vars(json_decode(file_get_contents("http://graph.facebook.com/RDTATTOOANDPIERCING")));
echo $facebook['about'];
?>
这是var_dump
转换为数组之前的内容:
object(stdClass)#1 (20) { ["about"]=> string(60) "Red Dragon Tattoo & Piercing is devoted to inking Cincinnati" ["checkins"]=> int(144) ["description"]=> string(509) "Red Dragon has been open since Feb. 2009, After Gabriel started constructing J began to Fill the chairs with his large following, after only a few months we brought on Chuck and Jocelyn to help with the overwhelming amount of people ready to get tattooed in the Colerain area and we've been inking up Cincinnati since then. We appreciate artfull expressions, and can help you make your own statement to this world through your body. If it's a body piercing, or a tattoo, what better way to express yourself." ["general_info"]=> string(59) "Artists: J, Chuck Hagedorn, Jocelyn Taylor, Gabriel Lowe " ["hours"]=> object(stdClass)#2 (12) { ["mon_1_open"]=> string(5) "13:00" ["mon_1_close"]=> string(5) "20:00" ["tue_1_open"]=> string(5) "13:00" ["tue_1_close"]=> string(5) "20:00" ["wed_1_open"]=> string(5) "13:00" ["wed_1_close"]=> string(5) "20:00" ["thu_1_open"]=> string(5) "13:00" ["thu_1_close"]=> string(5) "20:00" ["fri_1_open"]=> string(5) "13:00" ["fri_1_close"]=> string(5) "20:00" ["sat_1_open"]=> string(5) "13:00" ["sat_1_close"]=> string(5) "20:00" } ["is_published"]=> bool(true) ["location"]=> object(stdClass)#3 (7) { ["street"]=> string(17) "9242 Colerain Ave" ["city"]=> string(10) "Cincinnati" ["state"]=> string(2) "OH" ["country"]=> string(13) "United States" ["zip"]=> string(10) "45251-2406" ["latitude"]=> float(39.239511218398) ["longitude"]=> float(-84.592958873707) } ["parking"]=> object(stdClass)#4 (3) { ["street"]=> int(0) ["lot"]=> int(1) ["valet"]=> int(0) } ["phone"]=> string(17) "+1 (513) 385-6500" ["price_range"]=> string(10) "$$$$ (50+)" ["talking_about_count"]=> int(97) ["username"]=> string(19) "RDTATTOOANDPIERCING" ["website"]=> string(20) "rdtattoopiercing.com" ["were_here_count"]=> int(535) ["category"]=> string(14) "Local business" ["id"]=> string(15) "151284611579488" ["name"]=> string(28) "Red Dragon Tattoo & Piercing" ["link"]=> string(43) "http://www.facebook.com/RDTATTOOANDPIERCING" ["likes"]=> int(835) ["cover"]=> object(stdClass)#5 (3) { ["cover_id"]=> float(4.636681470078E+14) ["source"]=> string(94) "http://sphotos-c.ak.fbcdn.net/hphotos-ak-ash3/s720x720/547023_463668147007798_1259271309_n.jpg" ["offset_y"]=> int(0) } }
正如您所看到的,它以 object(stdClass) 开头,而应该是一个数组,因此添加代码get_object_vars()
将返回一个数组格式而不是 stdClass,您可以从这里看到var_dump
