Php - Delete files older than 7 days for multiple folders - php

Question

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);
}

It seems that you need a recursive function, i.e. a function that calls itself. In this case it calls itself when it finds a subdirectory to scan/traverse.
function delete_files($current_path, $days) {
$files_in_current_path = scandir($current_path);
foreach($files_in_current_path as $file) {
if (!in_array($release_file, [".", ".."])) {
if (is_dir($current_path . "/" . $file)) {
// Scan found subdirectory
delete_files($current_path . "/" . $file, $days);
} else {
// Here you add your code for checking date and deletion of the $file
$filelastmodified = filemtime($current_path . "/" . $file);
if((time() - $filelastmodified) > $days*24*3600) {
if(is_file($current_path . "/" . $file)) {
unlink($current_path . "/". $file);
}
}
}
}
}
}
delete_files("your/startpath/here", 7);
This code starts in your specified start path. It scans all files in that directory. If a sub directory is found, there will be a new call to delete_files, but with that sub directory as a start.
