PHP help

gnomer

I have a string, which is a url.

I want my PHP script to simply stip the www. out of the url and remove a trailing slash if it has one.

Can anyone help me?

Thanks!

Sorry, but what do you mean by "guarantee the input"?

Thanks for all your help!

Basically, are you certain all input will be in the format you want; "http://www." || "www." etc. or are you likely to get the odd "j00suckdawtc0m!"

You've spent less than an hour ? on it ?

yes substr may do the trick if you can guarantee the input

I'm sorry but I can't get my head around those!

could I use if substr to get the first few characters and see if it is http://www. ?

Also would that be any slower?

Lol, sorry dude but I don't fully understand what you mean...

I think I will have to search the net for somebody else who fixed this...

yes you do that ...

not understanding is fine ... not willing to learn is a wrong.

You have a commercial blog there (well "commercial" at any rate)

You're wanting people to basically do coding for you for free. While I've no problem helping people out ... as was just said ... this is a lose lose situation

we've both given you advice on how to do it ... I would have thought we've been pretty helpful. Can't you try helping yourself a little bit ? and read through the link we've just given ? If you do .. and you're still stuck ... I'd assume we'll have no problems helping out.

gnomer, i'm sorry but i'm with forbairt here.

I gave you a link to the function that will help you exactly to extract what you need; I could write the regular expression for you in a couple of minutes but what's the point in that? you learn nothing, I waste time it's a lose/lose situation for both of us.

Instead what that link does is gives you the information to get your head around this problem yourself, you won't become a better programmer if you just post on forums to get everything spoon fed to you.

attempt it using the method i suggested if it doesn't work out, post back your attempt here we'll be only too glad to help, also have a read of this site: http://www.regular-expressions.info/

Also how do I use regexp?

Read this
http://ie2.php.net/manual/en/function.preg-match.php

forbairt

well a search on the whole string matching for the url and (http://)*(www.)*(.*)(/)* would mean if its there you'd match for it if its not you won't.

then you'd take the 3rd result ... and away you go ...

regexp is pretty powerful you can do whatever you want with it.

Take the first hit of www as in match for http://www. all other www's would be left happy.

great! but what about the trailing slash? how will I remove that?

You will be matching www. including the . so I dont think this would be an issue?

gnomer

That would not be ideal for the purpose.

What if somebody had a url like:

http://www.google.com/www

It would remove both of them, wouldn't it?.
