Get Last Part of URL PHP

Solution 1:

The absolute simplest way to accomplish this, is with basename()

echo basename('http://domain.com/artist/song/music-videos/song-title/9393903');

Which will print

9393903

Of course, if there is a query string at the end it will be included in the returned value, in which case the accepted answer is a better solution.

Solution 2:

Split it apart and get the last element:

$end = end(explode('/', $url));
# or:
$end = array_slice(explode('/', $url), -1)[0];

Edit: To support apache-style-canonical URLs, rtrim is handy:

$end = end(explode('/', rtrim($url, '/')));
# or:
$end = array_slice(explode('/', rtrim($url, '/')), -1)[0];

A different example which might me considered more readable is (Demo):

$path = parse_url($url, PHP_URL_PATH);
$pathFragments = explode('/', $path);
$end = end($pathFragments);

This example also takes into account to only work on the path of the URL.

Yet another edit (years after), canonicalization and easy UTF-8 alternative use included (via PCRE regular expression in PHP):

<?php

use function call_user_func as f;
use UnexpectedValueException as e;

$url = 'http://example.com/artist/song/music-videos/song-title/9393903';

$result = preg_match('(([^/]*)/*$)', $url, $m)

    ? $m[1]
    : f(function() use ($url) {throw new e("pattern on '$url'");})
    ;

var_dump($result); # string(7) "9393903"

Which is pretty rough but shows how to wrap this this within a preg_match call for finer-grained control via PCRE regular expression pattern. To add some sense to this bare-metal example, it should be wrapped inside a function of its' own (which would also make the aliasing superfluous). Just presented this way for brevity.

Solution 3:

You can use preg_match to match the part of the URL that you want.

In this case, since the pattern is easy, we're looking for a forward slash (\/ and we have to escape it since the forward slash denotes the beginning and end of the regular expression pattern), along with one or more digits (\d+) at the very end of the string ($). The parentheses around the \d+ are used for capturing the piece that we want: namely the end. We then assign the ending that we want ($end) to $matches[1] (not $matches[0], since that is the same as $url (ie the entire string)).

$url='http://domain.com/artist/song/music-videos/song-title/9393903';

if(preg_match("/\/(\d+)$/",$url,$matches))
{
  $end=$matches[1];
}
else
{
  //Your URL didn't match.  This may or may not be a bad thing.
}

Note: You may or may not want to add some more sophistication to this regular expression. For example, if you know that your URL strings will always start with http:// then the regex can become /^http:\/\/.*\/(\d+)$/ (where .* means zero or more characters (that aren't the newline character)).

Solution 4:

If you are looking for a robust version that can deal with any form of URLs, this should do nicely:

<?php

$url = "http://foobar.com/foo/bar/1?baz=qux#fragment/foo";
$lastSegment = basename(parse_url($url, PHP_URL_PATH));

Solution 5:

$id = strrchr($url,"/");
$id = substr($id,1,strlen($id));

Here is the description of the strrchr function: http://www.php.net/manual/en/function.strrchr.php

Hope that's useful!
