[英]Getting Education with Facebook Graph API in PHP
我正在尝试使用 stdclass 从 Facebook 的图表 API 获取教育信息。 这是数组:
"username": "blah",
"education": [
{
"school": {
"id": "[removed]",
"name": "[removed]"
},
"year": {
"id": "[removed]",
"name": "[removed]"
},
"type": "High School"
},
{
"school": {
"id": "[removed]",
"name": "[removed]"
},
"year": {
"id": "[removed]",
"name": "[removed]"
},
"type": "College"
}
],
如何使用 PHP 到 select 类型为“college”的那个? 这是我用来阅读它的内容:
$token_url = "https://graph.facebook.com/oauth/access_token?"
. "client_id=[removed]&redirect_uri=[removed]&client_secret=[removed]&code=".$_GET['code']."";
$response = file_get_contents($token_url);
parse_str($response);
$graph_url = "https://graph.facebook.com/me?access_token="
. $access_token;
$user = json_decode(file_get_contents($graph_url));
所以名称将是 $user->name。
我尝试了 $user->education->school 但没有奏效。
任何帮助,将不胜感激。
谢谢!
JSON 文档中的教育是一个数组(注意它的项目被[ ]包围),所以你要做的是:
// To get the college info in $college
$college = null;
foreach($user->education as $education) {
if($education->type == "College") {
$college = $education;
break;
}
}
if(empty($college)) {
echo "College information was not found!";
} else {
var_dump($college);
}
结果将是这样的:
object(stdClass)[5]
public 'school' =>
object(stdClass)[6]
public 'id' => string '[removed]' (length=9)
public 'name' => string '[removed]' (length=9)
public 'year' =>
object(stdClass)[7]
public 'id' => string '[removed]' (length=9)
public 'name' => string '[removed]' (length=9)
public 'type' => string 'College' (length=7)
一个更简单的技巧是使用 json_decode 并将第二个参数设置为 true,这会强制结果为 arrays 而不是 stdClass。
$user = json_decode(file_get_contents($graph_url), true);
如果您使用 go 和 arrays,则必须将大学检索 foreach 更改为:
foreach($user["education"] as $education) {
if($education["type"] == "College") {
$college = $education;
break;
}
}
结果将是:
array
'school' =>
array
'id' => string '[removed]' (length=9)
'name' => string '[removed]' (length=9)
'year' =>
array
'id' => string '[removed]' (length=9)
'name' => string '[removed]' (length=9)
'type' => string 'College' (length=7)
虽然两者都是有效的,但在我看来,你应该使用 go 和 arrays,它们更容易、更灵活地完成你想做的事情。
