[kristijan]

hi,

$Text = ereg_replace("[[:alpha:]]+://[^{<>[:space:]]+[[:alnum:]/]",} "<a href=\"\0\" target=\"_blank\">\0</a>", $Text);

it displays http://www.myurl.com but not www.myurl.com

can somebody help please?

many thanks

Give this a try:

<?php
$text = preg_replace("/^(http:\/\/)?([^\/]+)/i", "<a href=\"\\0\" target=\"_blank\">\\0</a>", $text);
echo $text[2];
?>

The original script is from http://www.php.net/manual/en/function.preg-match.php but I modified it to match what your trying to do. The original script is:

<?php
preg_match("/^(http:\/\/)?([^\/]+)/i", "http://www.php.net/index.html", $matches);
echo $matches[2];
?>

Hi Rpanning,

your pattern matches everything from the beginning of the string until the first slash. So if $text was
"it displays http://www.myurl.com but not www.myurl.com"
you would match the bold part.

Kristijan,

here's one that will match any sequence of characters starting with 'http://' or 'www.', adding 'http://' in the link if necessary.

$text = preg_replace("#(http://([^{\s]+))|(www.[\s]+)#i",} "<a href=\"http://$2$3\">$1$3</a>", $text);

Note that anything following http:// or www. until the next space is considered to be a url, so it may create invalid links like www.1. To change this, you might want to break down the [^\s]+ into more specific subpattern.

Hope this helps,

But if a link doesn't begin with www?
See wwitv.com . Will be good to use a syntax in order the parser be able to distinguish between the urls and simple words?

well, it's somewhat difficult to decide what is supposed to be a url if you ommit the [url]http://[/url]

e.g.
- some alphanumeric stuff (plus -? plus _? I'm not sure if this is allowed) followed by a period as optional subdomain

• followed by the domain (alphanumeric and - I think)

• followed by a period

• followed by 2 to 6 letters as top level domain

• optionally followed by some other alphanumerics and /-_. in case there is a path given.

Shouldn't be too hard to put that into the regex, you just need to decide what you suppose to be a url.

However, I'd probably leave it as it is unless it is required to get more exact matches. Bye the way, did you notice that this board doesn't parse your example wwitv.com but does parse those starting with www.
😉

No, I'd really not recommend to do this, at least not in the way I outlined.

Take a look at these two strings
wwitv.com
mysql.exe

For you it's easy to see that the latter is more likely to be a filename rather than a url, but you'd probably have to admit that the pattern really is similar.

Sure, you could set up (and maintain) a list of valid top level domains to use in your regex, but I wouldn't want to do that.

What about e-mails, all the emails look like same, what is the tring manipulation in that occasion?
