标签: php mysql arrays echo

我需要一些PHP编码帮助来构建一个回显来显示数据库查询的结果...(列出已登录用户的朋友?)我已经构建了大部分内容,但我不知道如何回显结果数据并将其链接到他/她的个人资料?任何帮助将不胜感激...也许是如何写出来的代码片段?

这是我的代码:

$query = mysqli_query($db_conx, $sql);
$numrows = mysqli_num_rows($query);
if ($numrows > 0){
while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){
    array_push($my_friends, $row["user2"]);
    array_push($my_friends, $row["user1"]);
}
//remove your id from array
$my_friends = array_diff($my_friends, array($u));
//reset the key values
$my_friends = array_values($my_friends);
mysqli_free_result($query);
} else {
    echo "You have no friends.";
}

// Build My friends From Results
     ****this is where I need help with*****

if (array_key_exists('0', $my_friends)){
    $sql = "SELECT user1, user2 
    FROM friends 
    WHERE (user1='$u' OR user2='$u')
    AND accepted='1'";      
    $result = mysqli_query($db_conx, $sql);
    while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) {

$my_friends = "<a href='user.php?u=".$result."'>". $row['avatar']. '&nbsp'. $row['firstname']. '&nbsp' .$row['lastname'] ."</a>"; }
}
?>

Here is my html code:
<?php
echo "<li>$my_friends</li>"; 
  ?>

您正在使用html链接中的$result变量。将其替换为$row['id']或您用作GET参数的行属性,以查看用户的详细页面
