Your Javascript code should look like this:

a) did I get the right data back from the server?  If so, report success.
b) Otherwise, report failure to the user.

It doesn't matter what went wrong on the server side, if you're just 
reporting to the user.  MAke your PHP script return something (the word 
"good" for example), have your javascript look for that word, if it didn't 
get that word, report to the user "Something seems to be wrong".

Behind the scenes it might matter to you what went wrong with the PHP 
script, but it doesn't matter to the user at all.  You shouldn't be testing 
the http status code as a way to figure out if things were successful - test 
some data output by the PHP script, where that data is only sent if 
everything went correctly.
