我有这段代码：-
<?php
$xml = file_get_contents("http://graph.facebook.com/fql?q=SELECT%20url,%20normalized_url,%20share_count,%20like_count,%20comment_count,%20total_count,%20commentsbox_count,%20comments_fbid,%20click_count%20FROM%20link_stat%20WHERE%20url='http://www.facebook.com/nokia'");
echo $xml;
$obj = json_decode($xml);
print $obj;
print $obj->{'like_count'};
?>
它给了我以下错误：-
{"data":[{"url":"http:'/'/www.facebook.com'/nokia","normalized_url":"http:'/'/www.facebook.com'/nokia","share_count":1240,"like_count":8622663,"comment_count":287,"total_count":8624190,"commentsbox_count":2,"comments_fbid":404897301238,"click_count":10}]}
Catchable fatal error: Object of class stdClass could not be converted to string in C:'xampp'htdocs'nokia_app'test.php on line 5
我该如何纠正它？
在提出这些类型的问题之前，您需要研究 API 返回的内容。
$xml = file_get_contents("http://graph.facebook.com/fql?q=SELECT%20url,%20normalized_url,%20share_count,%20like_count,%20comment_count,%20total_count,%20commentsbox_count,%20comments_fbid,%20click_count%20FROM%20link_stat%20WHERE%20url='http://www.facebook.com/nokia'");
$obj = json_decode($xml);
var_dump($obj->data[0]->{'like_count'});
如果您确实需要使用数组中的数据，请尝试以下操作：
class ObjectToArray {
public static function convert( $object ) {
if( !is_object( $object ) && !is_array( $object ) ) {
return $object;
}
if( is_object( $object ) ) {
$object = get_object_vars( $object );
}
return array_map( 'ObjectToArray::convert', $object );
}
}
$aData = ObjectToArray::format($theObject);
print_r($aData);
