The correct way to delete all files older than 2 days in PHP

Question

Just curious

        $files = glob(cacheme_directory().\"*\");
        foreach($files as $file)
        {
            $filemtime=filemtime ($file);
                  


        

Answer 1

I reckon this is much tidier and easier to read and modify.

$expire = strtotime('-7 DAYS');

$files = glob($path . '/*');

foreach ($files as $file) {

    // Skip anything that is not a file
    if (!is_file($file)) {
        continue;
    }

    // Skip any files that have not expired
    if (filemtime($file) > $expire) {
        continue;
    }

    unlink($file);
}
