URLs

[J Huntley Palmer]

How may I capture the last /.../ in a url?

eg.. www.foo.com/foo/bar/baz/index.php?param=1

I want to capture 'baz'.

Thanks

Re: URLs

Use parse_url() function : http://www.php.net/function.parse-url

$url = www.foo.com/foo/bar/baz/index.php?param=1
$url_arr = explode ("//", parse_url($url) )

$i = count($url_arr) - 1;
$last_dir = $url_arr[$i];

Not tested yet, but i think its work.

Start from the end of the string and work backwards until you hit the
second /. Untested code follows:

$flag = false;
for ($i = strlen($url); $i > 0; $i--)
{
if ($url{$i} == '/')
{
if ($flag == true)
{
/* we have our match */
$url = substr($url, $i);
break;
}

/* got the first / */
$flag = true;
}
}

Whoops, misread your intent. Corrections follow (again, untested).

$flag = false;
$j = 0;
for ($i = strlen($url); $i > 0; $i--)
{
if ($url{$i} == '/')
{
if ($flag == true)
{
/* we have our match */
$url = substr($url, $i, ($j - $i));
break;
}

/* got the first / */
$flag = true;
$j = $i;
}
}

Just my $0.02:

$t = parse_url('www. foo.com/foo/bar/baz/index.php?param =1');
$t = pathinfo($t['path']);
$t = explode('/', $t['dirname']);
$t = array_pop($t);
var_dump('baz' == $t);
