PHP filemtime返回当前日期

Question

I want to get modified date of the file that is uploaded but it returns current time (which I guess it's because filemtime returns modified date of temp file so long story short how can I get the true modified date?

here is my code it's (laravel framework)

$file = $request->file;
dd(filemtime($file));

<?php
// outputs e.g.  somefile.txt was last modified: December 29 2002 22:16:23.

$filename = 'somefile.txt';
if (file_exists($filename)) {
    echo "$filename was last modified: " . date ("F d Y H:i:s.", filemtime($filename));
}
?>

The above code worked for, try it from your end, let me know, if any errors.
