replace text within a string?

Hello:

Could someone please tell me if it is possible to replace "www.mysite.com" with something like "***" or whatever in a string?

example:

$string = "Hello all, please visit my site at www.mysite.com!n";

so it says:

$string = "Hello all, please visit my site at ***!n";


Any ideas?

Thanks in advance!

I am thinking you are wanting to replace any url? in that case use something like:

$string = eregi_replace( "(http|https|ftp)://([[:alnum:]+-=%&:_.~?]+[#[:alnum:]+]*)",
"***",
$string);

Hi Matt:

Thanks for the reply!

That works great if they have the "http://" but what if the went like "www.mysite.com" or even "mysite.com"?

Is there anyway to get around that?

u can detect www.somesite.tld by adding www in first part of regex like


but i don't think that u can detect somesite.com

or u can, but it would also detect numbers of 3.14 or other stuff...


and matt, a pro like u should use pcre, not ereg ;)
