[SOLVED] PHP Parse URL - Domain returned as path when protocol prefix not present

PHP Parse URL - Domain returned as path when protocol prefix not present

I am trying to parse URL's in PHP where the input could be any of the following:

Code:

$info = parse_url('http://www.domainname.com/');
print_r($info);

$info = parse_url('www.domain.com');
print_r($info);

$info = parse_url('/test/');
print_r($info);

$info = parse_url('test.php');
print_r($info);

Returns:

Array
(
    [scheme] => http
    [host] => www.domainname.com
    [path] => /
)
Array
(
    [path] => www.domain.com
)
Array
(
    [path] => /test/
)
Array
(
    [path] => test.php
)

The problem you can see is the second example where the domain is returned as a path.

Solution

This gives the right results but the file needs to start with a slash:

parse('http://www.domainname.com/');
parse('www.domain.com');
parse('/test/');
parse("/file.php");

function parse($url){
    if(strpos($url,"://")===false && substr($url,0,1)!="/") $url = "http://".$url;
    $info = parse_url($url);
    if($info)
    print_r($info);
}

and the result is :

Array
(
    [scheme] => http
    [host] => www.domainname.com
    [path] => /
)
Array
(
    [scheme] => http
    [host] => www.domain.com
)
Array
(
    [path] => /test/
)
Array
(
    [path] => /file.php
)
