PHP解析XML與使用simplexml_load_file

Question

什麼是解析XML飼料，看起來像這樣的方式：

<string xmlns="http://vs-social-feed/"> 
{ "response": "success", "message": "", "feed": 
[ 
{"SocialId":105,"Type":2,"Id":"202297433163449_956836567709528","Url":"https://www.facebook.com/vsmag/photos/a.209641845762341.52114.202297433163449/956836567709528/?type=3","Text":"Hold your tongue!\n\nStacy Martin by Ellen von Unwerth official for Vs.

] 
} 
</string> 

我試圖與使用simplexml_load_file，的file_get_contents，json_decode和JSON編碼，但沒有任何運氣。

Answer 1

它是JSON數據不是XML。 PHP內置了json_decode（）函數來解析json數據。

試試這個代碼：

<?php 

$data = '{ "response": "success", "message": "", "feed":[{"SocialId":105,"Type":2,"Id":"202297433163449_956836567709528","Url":"https://www.facebook.com/vsmag/photos/a.209641845762341.52114.202297433163449/956836567709528/?type=3","Text":"Hold your tongue!\n\nStacy Martin by Ellen von Unwerth official for Vs.

$obj = json_decode($data); 
echo "<pre>"; print_r($obj->feed); echo "</pre>"; 

?>
