来自数据库的其中一个字段由","分隔。如(1,2,3,4,5) 这是我使用的代码:
$result = mysqli_query($con, "SELECT * FROM login WHERE phone=$user");
while ($row = mysqli_fetch_array($result)) {
$friends = $row['friends'];
$data = $friends;
$arr = explode(',', $data);
$today = date("d F", strtotime($row['time']));
$hour = date('g:i',
strtotime($row['time']));
if ($today < $row['time']) {
$today;
} else {
$today = $hour;
};
for ($i = 0; $i < count($arr); $i++) {
$friend = array($data);
foreach($friend as $value) {
echo "
<div class='contacts_item sep_cont'>
<img class='user_img' src='".$row['picture']."'>
<div class='contacts_title'>".$arr[$i]."<div class='time'>".$today."</div></div>
<div>".$row['name']."</div> </div> ";
}
}
}
有什么建议吗?

如果我理解你想要什么,我认为你可以创建一个只包含登录和朋友之间关系的表,如
TABLE login_friends
id | login_id | friend_id |
1 | 1 | 2 |
2 | 1 | 3 |
3 | 2 | 3 |
