Re: [PHP3] \n's et al From: christopher wright (chris <email protected>)

addslashes is just to escape those things that need escaping like quotes, it
won't do this job. For future reference to anyone else with the same
problem - the answer was this:

$foo="\\n\\n--- quoted ------------\\n>".str_replace("\r\n","\\n>",$foo)

which is more or less what Philip Diller kindly posted and provides me with
a single line of text suitable for use in a javascript variable written by
php.
