[php] PHP - Move a file into a different folder on the server

I need to allow users on my website to delete their images off the server after they have uploaded them if they no longer want them. I was previously using the unlink function in PHP but have since been told that this can be quite risky and a security issue. (Previous code below:)

if(unlink($path.'image1.jpg')){ 
     // deleted
}

Instead i now want to simply move the file into a different folder. This must be able to be done a long time after they have first uploaded the file so any time they log into their account. If i have the main folder which stores the users image(s):

user/

and then within that a folder called del which is the destination to put their unwanted images:

user/del/

Is there a command to move a file into a different folder? So that say:

user/image1.jpg

moves to/becomes

user/del/image1.jpg

use copy() and unlink() function

$moveFile="path/filename";
if (copy($csvFile,$moveFile)) 
{
  unlink($csvFile);
}

If you want to move the file in new path with keep original file name. use this:

$source_file = 'foo/image.jpg';
$destination_path = 'bar/';
rename($source_file, $destination_path . pathinfo($source_file, PATHINFO_BASENAME));

Use the rename() function.

rename("user/image1.jpg", "user/del/image1.jpg");

Use file this code

function move_file($path,$to){
   if(copy($path, $to)){
      unlink($path);
      return true;
   } else {
     return false;
   }
 }

Create a function to move it:

function move_file($file, $to){
    $path_parts = pathinfo($file);
    $newplace   = "$to/{$path_parts['basename']}";
    if(rename($file, $newplace))
        return $newplace;
    return null;
}

Some solution is first to copy() the file (as mentioned above) and when the destination file exists - unlink() file from previous localization. Additionally you can validate the MD5 checksum before unlinking to be sure

shell_exec('mv filename dest_filename');

I using shell read all data file then assign to array. Then i move file in top position.

i=0 
for file in /home/*.gz; do
    $file
    arr[i]=$file
    i=$((i+1)) 
done 
mv -f "${arr[0]}" /var/www/html/
