如何從Facebook Graph API回顯值

Question

我正在嘗試使用Facebook Graph API將員工Facebook個人資料的詳細信息導入我們的個人網站。

從以下URI獲取JSON對象： https : //graph.facebook.com/RDTATTOOANDPIERCING

我認為我將能夠簡單地轉換為數組並回顯所需的值。 但是我遇到了錯誤。

這是代碼：

<?php
$facebook = json_decode(file_get_contents("https://graph.facebook.com/RDTATTOOANDPIERCING"));
echo $facebook["about"];
?>

如果要查看正在渲染的源，請使用以下URL： http : //www.rdtattoopiercing.com/

提前謝謝！

Answer 1

沒有第二個參數的json_decode將返回一個對象，如果要返回數組，則添加第二個參數TRUE

嘗試這個：

$facebook = json_decode(file_get_contents("https://graph.facebook.com/RDTATTOOANDPIERCING"), TRUE);

echo $facebook["about"];

或使用object代替，如果您不想在第二個參數中添加TRUE

$facebook->about;

Answer 2

問題是它返回的是stdClass而不是數組，您可以使用var_dump($facebook)告訴我們，要將stdClass轉換為數組，請使用get_object_vars() 。
這是您的解決方案：

<?php
$facebook = get_object_vars(json_decode(file_get_contents("http://graph.facebook.com/RDTATTOOANDPIERCING")));
echo $facebook['about'];
?>

這是轉換為數組之前的var_dump ：

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) } }

如您所見，它以object（stdClass）開頭，而應該是一個數組，因此添加代碼get_object_vars()將返回數組格式，而不是stdClass，如您從此var_dump所看到的：

array(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.
