我搜索的東西后用戶名和ID更改

我有一個小型的社交網站，個人資料頁面和搜索頁面。這一切都可以正常工作，並且在菜單欄上通過profile.php?id=5（例如）顯示用戶名和鏈接。如何當我通過search.php搜索的東西，它一切正常，但後來當我搜索後重新加載一個頁面，突然用戶名顯示爲'P'和鏈接去profile.php?id=p 有誰知道發生了什麼？如果您需要更多信息，請告訴我，並提前致謝。代碼：我搜索的東西后用戶名和ID更改

<?php 

//capture search term and remove spaces at its both ends if the is any 
$searchTerm = trim($_GET['search']); 

//check whether the name parsed is empty 
if($searchTerm == "") 
{ 
    echo "Enter name you are searching for."; 
    exit(); 
} 

//database connection info 
$host = ""; //server 
$db = ""; //database name 
$user = ""; //dabases user name 
$pwd = ""; //password 

//connecting to server and creating link to database 
$link = mysqli_connect($host, $user, $pwd, $db); 

//MYSQL search statement 
$query = "SELECT * FROM users WHERE username SOUNDS LIKE '%$searchTerm%' or fname SOUNDS LIKE '%$searchTerm%' or lname SOUNDS LIKE '%$searchTerm%'"; 

$results = mysqli_query($link, $query); 
echo "<div class='searched'>Results for "; 
echo $searchTerm; 
echo "</div>"; 
/* check whethere there were matching records in the table 
by counting the number of results returned */ 
if(mysqli_num_rows($results) >= 1) 
{ 
    $output = ""; 
    while($row = mysqli_fetch_array($results)) 
    { 
     $output .="<div class='user'><a href='profile?id=$row[id]'>"; 
     $output .= "<img class='search_pp' src='" . $row['picture'] . "'/><br>"; 
     $output .= "<div class='search_username'> " . $row['username'] . "</div>"; 
     $output .= "<div class='search_full'>Full name: " . $row['fname'] . " " . $row['lname'] . "</div>"; 
     $output .= "<div class='search_sex'>" . $row['sex'] . "</div></div></a>"; 
    } 
    echo $output; 
} 
else 
    echo "No records of " . $searchTerm; 
?>

這是用戶名改變爲 'P'

<?php echo htmlentities($_SESSION['user']['username'], ENT_QUOTES, 'UTF-8'); ?>

而這正是在鏈路變爲 'P'

<a href="profile?id=<?php echo htmlentities($_SESSION['user']['id'], ENT_QUOTES, 'UTF-8'); ?>">

的ID，然後用戶的用戶名和編號在整個網站中都變爲'p'

1 - 您是否設置了喲你的$_SESSION['user']？

2 - 您可以在刷新前後執行var_dump($_SESSION['user']);以查看發生了什麼？
