>我有这个代码来上传图像并存储在数据库中我想先将其重命名为随机名称，然后上传并存储在数据库中我应该如何更改我的代码？请帮帮我！这是我的PHP代码：

$imageFile=$_FILES['image'];
$file_name = $imageFile['name'];
$target_path = "images/news/".$file_name;
if(move_uploaded_file($imageFile['tmp_name'], $target_path)) {
echo "<div id='"news'">";
 echo "Image : "."<br>".$file_name;
 echo "<br>"; 
 echo "Successfuly Uploaded!";
echo "<br>"; 

    $newstitle = $_POST['title'];
    $newscontent = $_POST['content'];
    $newsimage = "images/news/".$file_name;

    $sql="insert into news (news_title,news_content,news_image,news_date) values ('$newstitle', '$newscontent','$newsimage',' $newsdate')"; 
    if ($conn->query($sql) === TRUE)
    {
        echo "Image Stored in DB!</div>";
    } 
    else 
    {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}

试试这个
使用 $random = md5(uniqid("") . time()); 创建的随机文件名

这是重命名文件的工作代码

$imageFile = $_FILES['image'];
$file_name = $imageFile['name'];
$random = md5(uniqid("") . time());
$target_path = "images/news/" . $random.$file_name;
if (move_uploaded_file($imageFile['tmp_name'], $target_path)) {
    echo "<div id='"news'">";
    echo "Image : " . "<br>". $random . $file_name;
    echo "<br>";
    echo "Successfuly Uploaded!";
    echo "<br>";

    $newstitle = $_POST['title'];
    $newscontent = $_POST['content'];
    $newsimage = "images/news/" . $random. $file_name;

    $sql = "insert into news (news_title,news_content,news_image,news_date) values ('$newstitle', '$newscontent','$newsimage',' $newsdate')";
    if ($conn->query($sql) === TRUE) {
        echo "Image Stored in DB!</div>";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}
