static string|array pathinfo(string $path, int|null $options = null)

Unicode variant of pathinfo()

Kept for backwards compatibility only — it delegates to the native function. pathinfo() is UTF-8 safe on its own: the only characters it splits on, '/' and '.', cannot occur inside a multi-byte UTF-8 sequence, and PHP no longer classifies path bytes through LC_CTYPE. Verified identical output under the C, ISO8859-1, SJIS and UTF-8 locales.

This used to switch LC_CTYPE to 'en_US.UTF-8' for the duration of the call. That was both unnecessary and harmful: restoring the locale string afterwards does not restore PCRE's character tables, so from the first call onwards every regex without the /u modifier changed meaning process-wide — \w started matching bytes >= 0x80.

Parameters

string $path
int|null $options

Optional, one of PATHINFO_DIRNAME, PATHINFO_BASENAME, PATHINFO_EXTENSION or PATHINFO_FILENAME.

Return Value

string|array

static mixed parse_url(string $url, int $component = -1)

Parse a URL and return its components, UTF-8 safe

Parameters

string $url

The URL to parse. Invalid characters are replaced by _.
int $component

Specify one of PHP_URL_SCHEME, PHP_URL_HOST, PHP_URL_PORT, PHP_URL_USER, PHP_URL_PASS, PHP_URL_PATH, PHP_URL_QUERY or PHP_URL_FRAGMENT to retrieve just a specific URL component as a string (except when PHP_URL_PORT is given, in which case the return value will be an integer).

Return Value
