LEARN ABOUT PHP
parse_url
PARSE_URL(3) 1 PARSE_URL(3)
parse_url - Parse a URL and return its components
SYNOPSIS
mixed parse_url (string $url, [int $component = -1])
DESCRIPTION
This function parses a URL and returns an associative array containing any of the various components of the URL that are present.
This function is not meant to validate the given URL, it only breaks it up into the above listed parts. Partial URLs are also accepted,
parse_url(3) tries its best to parse them correctly.
PARAMETERS
o $url
- The URL to parse. Invalid characters are replaced by _.
o $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 VALUES
On seriously malformed URLs, parse_url(3) may return FALSE.
If the $component parameter is omitted, an associative array is returned. At least one element will be present within the array. Potential
keys within this array are:
o$scheme - e.g. http
o$host
o$port
o$user
o$pass
o$path
o$query - after the question mark
?
o$fragment - after the hashmark
#
If the $component parameter is specified, parse_url(3) returns a string (or an integer, 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.
CHANGELOG
+--------+---------------------------------------------------+
|Version | |
| | |
| | Description |
| | |
+--------+---------------------------------------------------+
| 5.4.7 | |
| | |
| | Fixed host recognition when scheme is omitted |
| | and a leading component separator is present. |
| | |
| 5.3.3 | |
| | |
| | Removed the E_WARNING that was emitted when URL |
| | parsing failed. |
| | |
| 5.1.2 | |
| | |
| | Added the $component parameter. |
| | |
+--------+---------------------------------------------------+
EXAMPLES
Example #1
A parse_url(3) example
<?php
$url = 'http://username:password@hostname:9090/path?arg=value#anchor';
var_dump(parse_url($url));
var_dump(parse_url($url, PHP_URL_SCHEME));
var_dump(parse_url($url, PHP_URL_USER));
var_dump(parse_url($url, PHP_URL_PASS));
var_dump(parse_url($url, PHP_URL_HOST));
var_dump(parse_url($url, PHP_URL_PORT));
var_dump(parse_url($url, PHP_URL_PATH));
var_dump(parse_url($url, PHP_URL_QUERY));
var_dump(parse_url($url, PHP_URL_FRAGMENT));
?>
The above example will output:
array(8) {
["scheme"]=>
string(4) "http"
["host"]=>
string(8) "hostname"
["port"]=>
int(9090)
["user"]=>
string(8) "username"
["pass"]=>
string(8) "password"
["path"]=>
string(5) "/path"
["query"]=>
string(9) "arg=value"
["fragment"]=>
string(6) "anchor"
}
string(4) "http"
string(8) "username"
string(8) "password"
string(8) "hostname"
int(9090)
string(5) "/path"
string(9) "arg=value"
string(6) "anchor"
Example #2
A parse_url(3) example with missing scheme
<?php
$url = '//www.example.com/path?googleguy=googley';
// Prior to 5.4.7 this would show the path as "//www.example.com/path"
var_dump(parse_url($url));
?>
The above example will output:
array(3) {
["host"]=>
string(15) "www.example.com"
["path"]=>
string(5) "/path"
["query"]=>
string(17) "googleguy=googley"
}
NOTES
Note
This function doesn't work with relative URLs.
Note
This function is intended specifically for the purpose of parsing URLs and not URIs. However, to comply with PHP's backwards com-
patibility requirements it makes an exception for the file:// scheme where triple slashes (file:///...) are allowed. For any other
scheme this is invalid.
