php - How can I add a time stamp to a file name uploaded with $_File before the file extension

Question

I have the following code

$image_path = $_FILES["p_image"]["name"].time();

it names the file image02.jpg1335279888

but i want it to be named image02_1335279888.jpg

How can I achieve that?

Answer 1

$path_parts = pathinfo($_FILES["p_image"]["name"]);
$image_path = $path_parts['filename'].'_'.time().'.'.$path_parts['extension']

Answer 2

你可以检查这个：

$file = $_FILES["p_image"]["name"];
$array = explode('.', $file);
$fileName=$array[0];
$fileExt=$array[1];
$newfile=$fileName."_".time().".".$fileExt;

Answer 3

$image_path = $_FILES["p_image"]["name"];
$extension = pathinfo($image_path)['extension'];
$file = "image02_".time().".".$extension."";
echo $file;

输出：

image02_1641041826.jpg
