str_replace() looks like a candidate

[hostfreak]

I agree with Andy. I gave it a shot, however there are some problems, maybe you or someone can expound on it:

[code]
<?php

function strip($domain) {
$domain = str_replace("www.","",$domain);
return $domain;
}

echo strip(www.domain.com);

?>
[/code]

For some reason all the periods are not showing.

After applying what wildteen88 said:
[code]
<?php

function strip($domain) {
$domain = str_replace("www.","",$domain);
return $domain;
}

echo strip('www.domain.com');

?>
[/code]

[wildteen88]

When calling the function it should be this:
[code]echo strip('www.domain.com');[/code]

Otherwise PHP will try to find the constants www, domain and com and join them to gether. When using a string it must be in quotes.

Also I have modified your title, please try to use descriptive titles when posting threads.

hi, the above code works fine.

How can I add to this code to change anything put in front...

i.e.

http://www.
http://
www.

etc, etc ....

[wildteen88]

Try this:
[code=php:0]function strip($domain)
{
    // get the segments of the url into an array
    // http://php.net/parse-url - for more info
    $url = parse_url($domain);

    $domain = str_replace("www.", "", $url['host']);

    return $domain;
}

echo strip('http://www.domain.com');
[/code]

[brown2005]

can anyone help with the above please. need this to work.

[trq]

[code=php:0]
$websites_website =  StripUrl($homepages_array['websites_website']);
[/code]

[brown2005]

nope still comes out blank

[brown2005]

rite i know why it doesnt work.

going on wildteen88's code, if someone put just domain.com and misses out both the http://www. then it echo's nothing, so how do i combat this please....

I'd have thought you were better off with a Regular Expression for this...

Check out preg_match() in the [url=http://www.php.net/manual/en/function.preg-match.php]PHP Documentation[/url]

Try something like this. This regexp removes the HTTP:// and the WWW. if it´s present in the link

ex:
[code=php:0]$string = "Here´s a string with a link to www.somesite.com bla bla";
echo preg_replace('/(http:\/\/)?www\.([-a-z0-9_][-a-z0-9_\.]+\.[a-z]{2,4}(\/[-a-z0-9_\.%&+\/=&]+)?)/is', '\\2', $string);[/code]

[brown2005]

I have now solved this myself. The above code does not work.

[brown2005]

Wildteen, sorry for posting the item twice, but you state the code above would do what I want it to do, but it doesnt, but I have solved it now.

Thanks for everyone's help.

[hostfreak]

brown2005, for my own knowledge, do you mind posting the code that you have made?

[wildteen88]

It worked fine for me.

[brown2005]

$string = "Here´s a string with a link to www.somesite.com bla bla";
echo preg_replace('/(http:\/\/)?www\.([-a-z0-9_][-a-z0-9_\.]+\.[a-z]{2,4}(\/[-a-z0-9_\.%&+\/=&]+)?)/is', '\\2', $string);

is that wat u are saying works fine?

[wildteen88]

Yes. When I run that code, I get this:
[quote]Here´s a string with a link to somesite.com bla bla[/quote]
Notice www. has gone from somesite.com. it also works if you have this: [nobbc]http://www.mysite.com[/nobbc], it'll return mysite.com

[brown2005]

http://mysite.com returns http://mysite.com not mysite.com

[wildteen88]

How are you using the code within your PHP script? and what version of PHP are you running.

[HuggieBear]

Here's the output I get, agrees with brown2005...

www.somesite.com -> somesite.com
http://www.somesite.com -> somesite.com
http://somesite.com -> http://somesite.com

[wildteen88]

Are yes, Just noticed that it only works if you have www. after http://. All whats needed is a tweak in the expression to get it to work, which I am trying to work on now.

try this:
[code=php:0]$string = "Here´s a http://www.mysite.com string with a link to www.somesite.com bla bla";

echo preg_replace('/(http:\/\/www.|http:\/\/|www\.)([-a-z0-9_][-a-z0-9_\.]+\.[a-z]{2,4}(\/[-a-z0-9_\.%&+\/=&]+)?)/is', '\\2', $string);[/code]


I did it the long way, using (http:\/\/www.|http:\/\/|www\.), it can be shortened but I'm an new to expressions

[brown2005]

also i have seen websites with https://www.somesite.com , but these only print out https://www.somesite.com to....
