echo "Sorry, there was a problem uploading your file.";
}
$photo=($_FILES['photo']['name']);
$photo2=($_FILES['photo2']['name']);

$photo4=($_FILES['photo4']['name']);

Answer 1

对每个文件使用以下代码：

$file = $_FILES['photo1']['name'];
$ext = pathinfo($file, PATHINFO_EXTENSION);
$photo = "newfile_".time().rand(5, 15).".".$ext
$targetx = $target . $photo;

Answer 2

为什么要使用时间戳？你确定它是独一无二的......因为如果两个图像具有相同的随机序列怎么办？

Answer 3

您可以使用一些哈希函数，如md5（）。只需将此功能应用于上传文件的名称即可。

Answer 4

试试这个：

$temp = explode(".", $_FILES["image"]["name"]);
$extension = end($temp);

$newfilename = time().rand().".".$extension;

Answer 5

$target_Path = $path_to_image_directory.basename($_FILES['url']['name']);
if(preg_match('/[.](jpg)|(jpeg)|(gif)|(png)$/', strtolower ($_FILES['url']['name']))) {
        move_uploaded_file( $_FILES['url']['tmp_name'], $target_Path );
}
$extention = explode(".",$_FILES['url']['name']); // Or use str function

$name = $imageName. "-" . RAND(10,100) . "." . $extention[1] ;
