PHP file Operations

1. Recursively get the number of files in the directory

function Getfilecount ($dir)
{

    if (!is_dir ($dir))
        return false;
    Open Directory
    $handle = Opendir ($dir);
    static $i = 0;
    while (false!== $file = Readdir ($handle))
    {
        if ($file! = '. ' && $file!== ')
        {
            $file = $dir. Directory_separator. $file;
            Determine if the current file is a directory
            if (Is_dir ($file))
            {
               GetFileCount2 ($file);

            }else
                $i + +;
        }
    }
    Closedir ($handle);
    return $i;
}

2. Recursively get the size of the directory

function GetFileSize ($dir)
{
    if (!is_dir ($dir))
        return false;
    Open Directory
    $handle = Opendir ($dir);
    static $num = 0;
    while (false!== $file = Readdir ($handle))
    {
        if ($file! = '. ' && $file!== ')
        {
            $file = $dir. Directory_separator. $file;
            Determine if the current file is a directory
            if (Is_dir ($file))
            {
                GetFileSize ($file);

            }else
                $num + = FileSize ($file);
        }
    }
    Closedir ($handle);
    return $num;
}
