Escaping javascript

[Anon]

I know howto escape quotes etc in php for Javascript however is there a function that can do this for me?

In perl I would use regex

$myvar =~ s/\'/\'/g; # escape ' as required by javascript
$myvar=~ s/[\n\r]//g; # remove line feeds

Is there a php function that does similar?

Here are a few very useful functions in PHP to escape special characters:
addslashes()
quotemeta()
htmlspecialchars()
