A simple PHP function to delete files older than a given age. Very handy to rotate backup or log files, for example...
<?php
/**
* A simple function that uses mtime to delete files older than a given age (in seconds)
* Very handy to rotate backup or log files, for example...
*
* $dir String whhere the files are
* $max_age Int in seconds
* return String[] the list of deleted files
*/
function delete_older_than($dir, $max_age) {
$list = array();
$limit = time() - $max_age;
$dir = realpath($dir);
if (!is_dir($dir)) {
return;
}
$dh = opendir($dir);
if ($dh === false) {
return;
}
while (($file = readdir($dh)) !== false) {
$file = $dir . '/' . $file;
if (!is_file($file)) {
continue;
}
if (filemtime($file) < $limit) {
$list[] = $file;
unlink($file);
}
}
closedir($dh);
return $list;
}
// An example of how to use:
$dir = "/my/backups";
$to = "my@email.com";
// Delete backups older than 7 days
$deleted = delete_older_than($dir, 3600*24*7);
$txt = "Deleted " . count($deleted) . " old backup(s):\n" .
implode("\n", $deleted);
mail($to, "Backups cleanup", $txt);
