php getting substring from a string

Question

I have the next URL: http://domen.com/aaa/bbb/ccc. How can I get the string after http://domen.com/?

Thanks a lot.

$sub = substr($string, 0, 10);

But if you actually want to parse the URL (that is, you want it to work with all URLs), use parse_url. For "http://domen.com/aaa/bbb/ccc", it would give you an array like this:

Array
(
    [scheme] => http
    [host] => domen.com
    [user] => 
    [pass] => 
    [path] => /aaa/bbb/ccc
    [query] => 
    [fragment] => 
)

You could then compile this into the original url (to get http://domen.com/):

$output = $url['scheme'] . "://" . $url['host'] . $url['path'];

assuming $url contains the parse_url results.

The substr example would be more appropriate to this question if it were of the substr($string, 17) variety. But regardless, parse_url should be used if applicable.

^ I didn't count the characters.

You can use PHP's split.

Your code will be something like:

$s = "http://domen.com/aaa/bbb/ccc";
$vals = split("http://domen.com/", $s);
// $v will contain aaa/bbb/ccc
$v = $vals[1];

PHP doesn't support array dereferencing, so split(...)[0] won't work. You'd need to store the result in a variable and then access the member...

http://php.net/manual/en/function.parse-url.php Might be the way to go.

If you simply want the string and the "http://domen.com/" part is fixed:

$url = 'http://domen.com/aaa/bbb/ccc';
$str = str_replace('http://domen.com/','',$url);

Use the regex for example like the function preg_replace

Try this:

preg_replace('/^.*?\w\//', '', $url)
