让我解释一下我实际上想要做什么。我将用户信息存储在名为“students_data”的 mysql 表中。在这里，现在我只想打印下表中除登录用户之外的这些名称。假设我总共有 5 个用户列表，其中包括我在表中的名字、姓氏和其他详细信息。 在表格中的 h2 标记下方，我想仅打印表格中的名字和姓氏，显然不包括我。
<?php
$serverName="localhost";
$userName="samsung";
$password="8198982039";
$dataBase="students_record";
$conn=mysqli_connect($serverName,$userName,$password,$dataBase);
$sql= "SELECT First_Name FROM students_data";
$result=mysqli_query($conn,$sql);
$cols=mysqli_fetch_array($result,MYSQLI_BOTH);
?>

最佳答案
请相应地调整变量，它会对您有用。谢谢:-
<?php
$serverName="localhost";
$userName="samsung";
$password="8198982039";
$dataBase="students_record";
$logged_in_user_id = $_SESSION['user_id']; // i assume that you store logged-in user in in session variable having name user_id
$conn=mysqli_connect($serverName,$userName,$password,$dataBase);
$sql= "SELECT First_Name,Last_name FROM students_data where id !='".$logged_in_user_id.""; // get all user except logged in user
$result=mysqli_query($conn,$sql);
$user_data = array();
$i = 0;
while($cols=mysqli_fetch_assoc($result,MYSQLI_BOTH);) {
$user_data[$i]['first_name'] = $cols['First_Name'];// get first name
$user_data[$i]['last_name'] = $cols['Last_Name']; // get last name
}
