Php 对于每个循环

我试图为我的论文制作一个web应用程序。 实际上，它几乎完成了，但我仍然需要找到一种方法将用户喜欢的内容存储在数据库中。我收集用户信息，尝试看看他或她喜欢的电影和保存在不同SNS中的用户数据元素之间是否存在关系。对于单个信息，它已经按应有的方式保存了内容。问题是，facebook使用数组和对象，我无法找到一种方法将所有喜欢的内容保存在一个字符串中（然后保存到数据库中）

正如你所看到的，对于语言、爱好、喜爱的运动员，我现在用一种丑陋的方式对其进行编码，以读取个人资料并存储它。问题是有些人有超过100个喜欢的人，用这种方式编码当然不方便。当我使用

对于每个it always bug…

如果您只想为单个表连接数组，请使用PHPs内爆函数

与此处提到的数组映射相结合

或者，按照评论中提到的方法对数据库进行正常化

    'favorite_athletes'     => implode(",", array_map(function($x) { return $x['name'];},$fbUserProfile['favorite_athletes']));
    'likes'               => implode(",", array_map(function($x){ return $x['name']}, $fbUserProfile['likes']['data']));

如果您只想连接数组，可以使用PHPs

内爆

函数。您不应该在单个数据库字段中将所有具有名称的like保存为长字符串。与其规范化数据库，不如为相似的信息使用一个不同的表，并使用一个单独的表链接这两个信息。这同样适用于所有其他连接的值。它总是错误的。这到底是什么意思

    'favorite_athletes'     => implode(",", array_map(function($x) { return $x['name'];},$fbUserProfile['favorite_athletes']));
    'likes'               => implode(",", array_map(function($x){ return $x['name']}, $fbUserProfile['likes']['data']));
