I have a dynamic url string which I am trying to convert the string to html bold string character.

For example
$url='http://www.experts-exchange.com'
$url=~s/(http:)/<b>$1<\/b>/ig;

Therefore $url='<b>http:</b>

This is not the output that I want. How do you change the regular expression to get my desired out that is
$url='<b>http://www.experts-exchange.com</b>'

Pls bare in mind that the url is dynamic.

If there is only URL in the string, use

$url='http://www.experts-exchange.com'
$url=~s/(http:)(.*)$/<b>$1$2<\/b>/ig;

If there is another text, you should define the end of url:

$url='http://www.experts-exchange.com something else'
$url=~s/(http:)(.*?)\s/<b>$1$2<\/b>/ig;

or limit characters that can be included into the url (not sure that I remember all chars, check this :)

$url=~s/(http:)([\w\-\&\?\d\.\/\\]+)/<b>$1$2<\/b>/ig;

$url = "<b>$url</b>";

Is that what you meant?
