smarty replace line breaks

问题

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.

回答1:

Try this if it works:

{$var|regex_replace:"/[\r\n]/" : " "}
