PHP Remove x Minutes old file – recursive

I need that function to delete 10 minutes old files from my project,
remove_x_minutes_old_files function required two parameters $path for directory path and $in_minutes for minutes how much old file you want to delete.
[php]
function remove_x_minutes_old_files($path,$in_minutes=10){
$minutes_in_seconds = $in_minutes*60;
$now_unix_time = strtotime(‘now’);
$d2 = array(‘.’,’..’);
$dirs = array_diff(scandir($path),$d2);
foreach($dirs as $pathKey=>$pathVal){
$new_path =$path.$pathVal;
if(is_dir($new_path)){
remove_ten_minutes_old_files($new_path.’/’);
} else {
if(($now_unix_time – filemtime($new_path) ) >=$minutes_in_seconds){
unlink($new_path);
}
}
}
}
[/php]
