smarty replace line breaks

At the time of writing this, the smarty.net website appears to be down.

Anyway, how do I replace line breaks with a space in a smarty variable? Is it something like this {$var|regex_replace:'[\r\n]':'s'} ? I tried it but it didn’t work.

Answer

Try this if it works:

{$var|regex_replace:"/[rn]/" : " "}
