too long

Question

What pattern should I use for glob function to filter only folders that contain numeric string.

this will show only folders with a single digit:

glob('/path/to/files/[0-9]')

What about folders with multiple digits or when is_numeric is true?

Answer 1

function filterFiles($path, $flag="", $ext="", $regex_pattern="") {
    if ($ext) $ext=".$ext";
    if ($flag=="files") $files=array_filter(glob("$path/*$ext"), "is_file");
    else if ($flag=="dirs") $files=array_filter(glob("$path/*$ext"), "is_dir");
    else $files=glob("$path/*$ext");
    if ($regex_pattern) foreach($files as $i=>$file) {
        if(!preg_match($regex_pattern, basename($file))){
            unset($files[$i]);
        }
    }
    $result=array_values($files);
    return $files;
}



$revPaths=filterFiles($path,"","","/^\d+$/");
