PHP preg_replace

Dear All,

I have this problem, please help me.
I want to replace www.google.com to http://www.google.com.com by using function preg_replace(), but i don't know how to do.

$tring = 'hey search for stuff at www.google.com';
$pat = '/www\.google\.com/';
$replace = 'http://www.google.com';
$new_string = preg_replace ($pat, $replace, $tring);

echo $new_string;

PHP:

 

Thanks,

what about if i want to change other word that not specific when user type the website with http://
example: www.google.com,www.yahoo.com,......................


Thanks

 

Do you mean you just want to add http:// onto whatever variable?

for that just use the .= operator.

$url = 'http://';
$url .= 'www.google.com';

The output of $url will now be http://google.com

 

Yes i mean like that, i mean that the variable depend on input if they type www.google.com it will convert to http://www.google.com, if www.yahoo.com it will convert to http://www.yahoo.com...........

thanks
