preg_replace() urls

[smithster]

Hi guys,

I have a complete link to an image which is dynamic so declared as a variable...

eg url = 'http://somelink.com/images/image.jpg'

I want to remove the url part with the exception of the image name and extention. So I'm looking to do something like this....

change url from 'http://somelink.com/image.jpg' to just image.jpg.

I've tried using preg_replace...

This works...

$url = 'http://somelink.com/images/image.jpg';
preg_replace('/http:\/\/somelink.com\/images\//', '', $url); 

This doesn't...

$link = 'http://somelink.com';
$url = 'http://somelink.com/images/image.jpg';
preg_replace('/'.$link.'\/images\//', '', $url); 

I'm guessing I need to do something to $link to escape the slashes but I don't have a clue what to do! Can anyone help please?

Thanks in advance

explode is the easiest to use.

$url = 'http://example.com/path/to/someimage.jpg';

$filename = end(explode('/',$url));

A couple options:

$url = 'http://example.com/path/to/someimage.jpg';
$fileName = basename($url);
echo $fileName; 

A bit more robust:

$url = 'http://example.com/path/to/someimage.jpg?foo=bar#fubar';
$fileName = basename(parse_url($url, PHP_URL_PATH));
echo $fileName;

I use explode a lot but I never knew you could do that!! Thank you this worked a treat!

@NogDog....

Thank you for your suggestion, I've used the explode function as it works nicely for me and there will never be any parameters to consider in the url.

Thanks guys
