Php – Delete files older than 7 days for multiple folders

i would like to create a PHP script that delete files from multiple folders/paths. I managed something but I would like to adapt this code for more specific folders.

This is the code:

<?php
function deleteOlderFiles($path,$days) {
  if ($handle = opendir($path)) {
    while (false !== ($file = readdir($handle))) {
      $filelastmodified = filemtime($path . $file);
      if((time() - $filelastmodified) > $days*24*3600)
      {
        if(is_file($path . $file)) {
          unlink($path . $file);
        }
      }
    }
    closedir($handle);
  }
}

$path = 'C:/Users/Legion/AppData/Local/Temp';
$days = 7;
deleteOlderFiles($path,$days);
?>

I would like to make something like to add more paths and this function to run for every path. I tried to add multiple path locations but it didn’t work because it always takes the last $ path variable. For exemple:

$path = 'C:/Users/Legion/AppData/Local/Temp';
$path = 'C:/Users/Legion/AppData/Local/Temp/bla';
$path = 'C:/Users/Legion/AppData/Local/Temp/blabla';
$path = 'C:/Users/Legion/AppData/Local/Temp/blalbalba';
$days = 7;
deleteOlderFiles($path,$days);

Thank you for you help!

The simple solution, call the function after setting the parameter not after setting all the possible parameters into a scalar variable.

$days = 7;

$path = 'C:/Users/Legion/AppData/Local/Temp';
deleteOlderFiles($path,$days);

$path = 'C:/Users/Legion/AppData/Local/Temp/bla';
deleteOlderFiles($path,$days);

$path = 'C:/Users/Legion/AppData/Local/Temp/blabla';
deleteOlderFiles($path,$days);

$path = 'C:/Users/Legion/AppData/Local/Temp/blalbalba';
deleteOlderFiles($path,$days);

Alternatively, place the directories in an array and then call the funtion from within a foreach loop.

$paths = [];
$paths[] = 'C:/Users/Legion/AppData/Local/Temp';
$paths[] = 'C:/Users/Legion/AppData/Local/Temp/bla';
$paths[] = 'C:/Users/Legion/AppData/Local/Temp/blabla';
$paths[] = 'C:/Users/Legion/AppData/Local/Temp/blalbalba';

$days = 7;

foreach ( $paths as $path){
    deleteOlderFiles($path,$days);
}
