Domain Keyword

Haris · 11-25-2007, 12:59 AM

I want to fetch the keyword from the domain.

Currently, my code works with www.domain.com but doesn't work with www.domain.co.uk and www.domain.com.uk or any domain that ends with two extensions.

PHP Code:


			
$szPattern = '/^(http\:\/\/)?(www.)?(.*)\.(.*)$/';

Current Output with www.domain.com

Array ( [0] => http://www.domain.com [1] => http:// [2] => www. [3] => domain [4] => com )

Wrong output with www.domain.com.uk

Array ( [0] => http://www.domain.com.uk [1] => http:// [2] => www. [3] => domain.com [4] => uk )

The .com part should go with the other extension (uk) .

How about parse_url instead? Will that do the trick?

No, Adam. That won't help.

Well, what you could do.. is just use explode. Make sure the domain is formatted like: www.domain.com.uk or whatever (without slashes or beginning http://), and then just do this:

PHP Code:


			
/* First get rid of http:// and trailing slash */
$szDomain = 'www.domain.co.uk';
$szKeyword = explode('.', $szDomain);
echo $szKeyword[2];

The only error I see this having, if they enter something like: www.sub.domain.com for example, but even then, they shouldn't have the www in front, so it would still work.

Erm, I will try but I would prefer a more cleaner version. I'm heading for sleep and might think good solutions in the morning. ;)

Thanks, though.

That is a rather clean version.. also, if it works, why not use it if you can't find another way to do it?

I'd be tempted to use Andrew's anyway regardless. Regex isn't the fastest, as you'd expect, and if something can be achieved with increased performance, then I would be inclined to go for it.

php Code:

$szPattern = '/^(http\:\/\/)?([url]www.)?([/url][a-z0-9-\.]*)\.([a-z]{0,3})(\.[a-z]{0,2})?$/i';

Try that. It's probably buggy. You should be more strict in what you are allowing for each section. Because the domain name doesn't allow every character. The TLD doesn't allow every character and is usually only a certain length.

Mhmm,

PHP Code:


			
        $szURL = parse_url($szString);
        $szDomain = $szURL['path'];
        $szKeyword = explode('.', $szDomain);
        echo $szKeyword[1];
