Defaults to the current working directory. * @param string $ds the directory separator to be used in the normalized result. Defaults to `DIRECTORY_SEPARATOR`. * @return string * @since 4.3.5 */ public static function absolutePath( string $to, ?string $from = null, string $ds = DIRECTORY_SEPARATOR, ): string { $to = static::normalizePath($to, $ds);

// Already absolute? if ( str_starts_with($to, $ds) || preg_match(sprintf('/^[A-Z]:%s/', preg_quote($ds, '/')), $to) ) { return $to; }

if ($from === null) { $from = FileHelper::normalizePath(getcwd(), $ds); } else { $from = static::absolutePath($from, ds: $ds); }

return $from . $ds . $to;…
