| * This method is the primary defense against directory traversal and | ||
| * path manipulation attacks. It ALWAYS normalizes the input (see {@see normalizePath}), | ||
| * converting slash and unicode variants to a canonical absolute path. | ||
| * | ||
| * After normalization, any path containing '/..' segments (traversal attempts) is rejected. | ||
| * Normalized paths like '//foo//bar' are allowed and become '/foo/bar'. | ||
| * | ||
| * @param string $path Untrusted or user-supplied path to check. | ||
| * @return bool True if the path is safe, false otherwise. |

There was a problem hiding this comment.
The doc string is longer than the implementation of the the function, it literally describes the implementation.
IMHO this is not a good thing because docs are not always kept up to date and will differ from implementation and then it just confuses at some point.
Better to just state the intent of the method and make the code itself self explaining.
