parse_urlParse a URL and return its components
&reftitle.description;
intstringarraynullfalseparse_urlstringurlintcomponent-1
This function parses a URL and returns an associative array containing any
of the various components of the URL that are present.
The values of the array elements are not URL decoded.
This function is not meant to validate
the given URL, it only breaks it up into the parts listed below. Partial and invalid
URLs are also accepted, parse_url tries its best to
parse them correctly.
&reftitle.parameters;
url
The URL to parse.
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 int).
&reftitle.returnvalues;
On seriously malformed URLs, parse_url may return
&false;.
If the component parameter is omitted, an
associative array is returned. At least one element will be
present within the array. Potential keys within this array are:
scheme - e.g. http
hostportuserpasspathquery - after the question mark ?fragment - after the hashmark #
If the component parameter is specified,
parse_url returns a string (or an
int, in the case of PHP_URL_PORT)
instead of an array. If the requested component doesn't exist
within the given URL, &null; will be returned.
As of PHP 8.0.0, parse_url distinguishes absent and empty
queries and fragments:
Previously all cases resulted in query and fragment being &null;.
Note that control characters (cf. ctype_cntrl) in the
components are replaced with underscores (_).
&reftitle.changelog;
&Version;&Description;8.0.0parse_url will now distinguish absent and empty queries
and fragments.

&reftitle.notes;
This function may not give correct results for relative or invalid URLs,
and the results may not even match common behavior of HTTP clients.
If URLs from untrusted input need to be parsed, extra validation is
required, e.g. by using filter_var with the
FILTER_VALIDATE_URL filter.
This function is intended specifically for the purpose of parsing URLs
and not URIs. However, to comply with PHP's backwards compatibility
requirements it makes an exception for the file:// scheme where triple
slashes (file:///...) are allowed. For any other scheme this is invalid.
