If you have a missing close-bracket "}" somewhere in your code, the PHP parser tells you that the error is at the last line.  If you have a multi-hundred or thousand line file, this makes life a bitch.

Rasmus tells me that the reason for this behavior is because functions can be nested, which means that:

function a 
  function b
is OK. This is a silly feature.  Why do you have it, for scoping reasons?  It means that you can't effectively tell where syntax errors occur.

Suggestion: Either make nested functions turned off by default but you can turn them on with a PHP global variable, like $PHP_BIZARRO_NESTED_FUNCTIONS = 1;


have the parser syntax set up so that it marks where a possible syntax error occurred (IOW it sees a possible nested function, but it could also be a syntax error), and if it reaches the end of the file with a missing "}" or two, that it displays the location where it parsed the nested function.

brackets are used for other controll structures as well, so disabling nested functions do not solve the problem. ->bogus

nested functions make for grate walkers in recursive functions

if the scope is limited with in the outer function  (witch it isn't)
AND can use same variables as outer function
