stripping data from string

Anon

I have a large set of urls that I need to strip a section of data out of each url.

The urls are in the following format...

http://www.somewhere.com/something/102-3336229-5955368

http://www.somewhere.com/somethingelse/102-3336229-5983209

http://123.somewhere.com/whatever/303-336229-5955368

I need something that will search for the xxx-xxxxxx-xxxxxxx part of the url and remove it and return the rest of the url.

How could I go about doing this?

Thanks in advance for any help.

Bryan,

Try this

$url = 'http://www.somewhere.com/something/102-3336229-5955368';
$parts = explode ( "/", $url );
$last_part = array_pop ( $parts );
print $last_part;

Should work fine.

Thanks Neil,

However, I left out one important part.

The xxx-xxxxxxx-xxxxxxx isn't always at the end. There is sometimes more after it, such as:

http://www.somewhere.com/something/102-3336229-5955368/somethingelse

Thanks for the help

And...

Once I find the xxx-xxxxxxx-xxxxxxx, I want to keep the portion of the url that occurs before the xxx-xxxxxxx-xxxxxxx and drop everything else.

Thanks

Regular expressions. But from your examples, I'm not sure what you're looking for. Your first two examples have seven digits in the middle component of the numeric string; the third has only six.

$url =
ereg_replace('(([0-9])-([0-9])-([0-9]*))','',$url);

This will strip all sets of three numbers separated by hyphens.

1-2-3 will be stripped as well as 123-4566-6789,

Thanks Steve!

That was exactly what I was looking for.
