php - 上传文件重命名

Question

我有这个非常基本的文件上传脚本：

$prefix = "sitename";
$targetPath = "/uploads/sitename/"

$prefix = $prefix . "_";

$filename = $prefix . md5(basename($_FILES['image']['name'])) . md5(time()) . rand(11111,99999); 

if(move_uploaded_file($_FILES['image']['tmp_name '], $targetPath)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']). " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";
}

但我需要将图像重命名为，$filename然后才能移动到$targetPath. 我该怎么办？

Answer 1

您可以在 的第二个参数中指定新文件名move_uploaded_file。

例子：

move_uploaded_file($_FILES['image']['tmp_name'], $targetPath . $filename);
