Parse_url

(PHP 4, PHP 5)

Parse_url-parses the URL and returns its components

Description

Array parse_url (string $url)

This function parses a URL and returns an associative array containing the various components that appear in the URL.

This function is not used to verify the validity of a given URL, but to decompose it into the parts listed below. Incomplete URL is also accepted, and parse_url () will try to parse it as correctly as possible.

Parameters.

Url

URL to be parsed

Return value

For seriously unqualified URL,parse_url (), it may return FALSE and issue E_WARNING. Otherwise, an associative array is returned with at least one component:

Scheme-such as http

Host

Port

User

Pass

Path

Query-in the question mark? After that

Fragment-after the hash symbol #

Example

Example 2369. Parse_url () example

The above example outputs:

Array ([scheme] = > http [host] = > hostname [user] = > username [pass] = > password [path] = > / path [query] = > arg=value [fragment] = > anchor)

Annotation

Note: this function cannot be used for relative URL.

Note: parse_url () is specifically used to parse URL rather than URI. However, to comply with the need for PHP backward compatibility, three slashes (file:///...) are allowed for the file:// protocol. No other agreement can do that.
