replacing www... with hyperlink

[monomaniac21]

hi all i want to replace all entries of beginning with 'www.' and
ending with ' ' with a hyperlink to that substring such as:

www.google.com := <a href="www.google.com">www.google.com</>

can anyone tell me the easiest way to do this?

regards

You'll want to put an 'http://' in the href attribute, too.

The best way to do this is to use preg_replace, see the manual at
http://php.net/preg_replace.

well i figured out my own way of doing this cos the problem kept
bugging me and ive added her for anyone else who is interested. if
anyone else knows of a more efficient way id love to hear it. im not
sure but i think exploading a string then searching each array value
might be bettered by a function that just performed a search and
replace on the string.

$para1 = "sdfsdf dsf dsfsd www.dsafads.com";
$para1_arr = explode(' ',$para1);
$i = 0;
foreach ($para1_arr as $value) {
$newarr[$i] = $value;
if (strstr($value, 'www.') != FALSE) {
$value = "<a href='http://$value'>$value</a>";
$newarr[$i] = $value;
}
$i = $i + 1;
}
$para1 = implode(' ', $para1);

$para1 = implode(' ', $para1);

should be : $para1 = implode(' ', $newarr);

oops!

How will that work with mail.yahoo.com or groups.google.com ?

Not, but as the OP stated: he only wants links beginning with www.
Personally, I'd check for '|[a-z]+://|', which will find protocols, and
maybe put an extra check in for words starting with 'www.'.
