我需要以下脚本的帮助，我是 JSON 新手，需要将一些数据存储到 MYSQL 数据库。 我怎样才能做到这一点？或者，您是否可以协助编写脚本并详细解释如何使用 Facebook Javascript SDK 将用户登录信息存储到 MYSQL 数据库。存储他们的姓名和 ID
<?php
$sApplicationId = 'YOUR_APPLICATION_ID';
$sApplicationSecret = 'YOUR_APPLICATION_SECRET';
$iLimit = 99;
?>

最佳答案
将数据存储在数组中，然后使用 json_encode()。
看看here .
在 for 循环中:
for (var i = 0; i < friend_data.length; i++) {
results += '<div><img src="https://graph.facebook.com/' + friend_data[i].id + '/picture">' + friend_data[i].name + '</div>';
$.ajax({
type: "POST",
url: "some.php",
data: { id : friend_data[i].id, name: friend_data[i].name }
});
}
在 some.php 中:
$tmpArray = array('id' => $_POST['id'], 'name' => $_POST['name']);
$output = json_encode($tmpArray); // <-- save this in your db, if you want to store a JSON string, but it doesn't seem to be optimized. You'd better to save ID and name.
