[SOLVED] preg_replace whitespace for underscore...

[socalnate]

$link = preg_replace(" ", "_", $link);

 

I get an error

 

Warning: preg_replace() [function.preg-replace]: Empty regular expression in

 

So how do you represent whitespace in preg_replace?

I've not tested but a google search gave me these:

 

ALL WHITESPACE NOT JUST THE SPACE CHARACTER:

$after=preg_replace('/\s+/','',$before);

 

ALL SPACES:

$nospaces = str_replace(' ', '', $input);

 

NEWLINE AND CARRIAGE RETURN:

(added just in case you needed it too)

str_replace("\n", '', $input);
str_replace("\r", '', $input);

 

EDIT:  Decided to come back and identify the code as code (sorry)

Found an ereg_replace that worked perfect

 

$link  = ereg_replace("[ \r\t\n]+", "_", $link);

$link = strtolower($game_name_link1);

echo "<a href=\"http://www.mysite.com/portal/{$link}.html\"
