how to extract certain bit from string?

[natasha_thomas]

Folks,

 

http://natty.com/p/bh-fitness-class-indoor-magnetic-exercise-bike-2-years-parts-/detail/b004r2wuak/fitness-spinning.html

 

From this url String, i want to extract the last part of string which is, "fitness spinning".

 

This URL is dynamic an can have any value in that last bit, so how to extract anything btween Two Forward slashes just before .html?

 

Note: It can not be extracted with GET as its not how its designed.

 

Thanks

Natasha

try this

<?php
$url="http://natty.com/p/bh-fitness-class-indoor-magnetic-exercise-bike-2-years-parts-/detail/b004r2wuak/fitness-spinning.html";
preg_match_all("/\/\w{2,20}-\w{2,20}.html/", $url, $matches);
print"<pre>";
print_r($matches);
print"</pre>";
$last = $matches[0][0];
$take_out = array('/', '-', '.html');
$put_in = array('', ' ', '');
$last = str_replace($take_out, $put_in, $last);
print"$last";
?>

 

it outputs this

Array
(
    [0] => Array
        (
            [0] => /fitness-spinning.html
        )

)
fitness spinning

Hey nat.

 

<?php
function getLastPath($url) {
        $trim_path = trim($url, '/');
        $parts = explode('/', $trim_path);
        $last = end($parts);

        return $last;
   }

$insert_url = "http://natty.com/p/bh-fitness-class-indoor-magnetic-exercise-bike-2-years-parts-/detail/b004r2wuak/fitness-spinning.html";

    echo getLastPath($_SERVER['REQUEST_URI']);//get current page
    echo '<br />';
    echo getLastPath($insert_url);//get inserted url
?>

Thansk but seems this code is not working for the below URL:

Here's how to get the position before too.

 

<?php
function getSecondLastPath($url) {
        $path = parse_url($url, PHP_URL_PATH);
        $trim_path = trim($path, '/');
        $positions = explode('/', $trim_path);

        if (substr($path, -1) !== '/') {
            array_pop($positions);
        }
        return end($positions);
   }

$insert_url = "http://natty.com/p/bh-fitness-class-indoor-magnetic-exercise-bike-2-years-parts-/detail/b004r2wuak/fitness-spinning.html";

    echo getSecondLastPath($_SERVER['REQUEST_URI']);//get current page
    echo '<br />';
    echo getSecondLastPath($insert_url);
    echo '<br />';
?>
